32bit chroot help needed

i've set the 32bit chroot on my multilib install and i'd like to start using some 32bit apps only:
1. oracle-xe - doesn't work on 64 bit and the installation from the ebuild on the bugzilla doesn't let me run the configurator. the sabayon ebuild works but when i try to configure with the script it gives a lot of errors of some nls thing and doesn't work when i try to connect.
2. i wish to install firefox but it needs a lot of stuff, including the xorg and kde. is there a way to install it without installing the whole system?!
3. i need to install sun-jdk but also it pushes:

i do not want all this stuff inserted into a 32bit chroot if it is not needed.

I have firefox installed in a 32-bit chroot without any xorg-server, but I haven't bothered with java.

It's all a matter of USE flags really, but you will need quite a few X libraries.

I wanted an absolutely minimal chroot, so I actually strarted by setting USE="-*" in make.conf, and only added what I absolutely needed (and made good use of /etc/portage/package.use).

This is my entire USE section in that make.conf;

They are all dependencies which are needed, and you will HAVE to compile most of them at some point.

This is why I think 64-bits is a bad idea if you need to do any significant 32-bit stuff - You will effectively end up having two copies of Gentoo installed; a 32-bit one and a 64-bit one because of all the compile-time and run-time dependencies.

64-bit Gentoo has very good 32-bit support ONLY because the devs work so hard to make the 32-bit emul library dependencies link correctly; As soon as you leave that environment you're in the same 32/64-bit hell that the other distros have to deal with.

If you could make a 32-bit binpackage of that software on another machine, it may be possible to make an overlay ebuild and use that to install it on your system to run under the emul libraries, but that's waaay out of my depth.

so, correct me if i'm wrong: if i make a packaged version of sun-jdk and of the 32bit packages that i need and then install them on my 64bit arch i could get them to work?!
as for java: why the h*** isn't there a way to compile it for 64bit?! now java is opensource and i don't really see why there isn't the possibility to compile it natively for 64bit arch.
the javac doesn't come for amd64 and this is really annoying since i need it to compile things!!!!

Did you mange it?
I got oracle-xe working nicely on amd64 using a modified ebuild found in sabayon overlay, and a 32bit compiled libaio.
I tested basic db creation and the apex.

svn co http://gimpel.ath.cx/svn/gimpel/dev-db/oracle-xe/
svn co http://gimpel.ath.cx/svn/gimpel/app-emulation/emul-linux-x86-libaio/

The emul is compiled with -march=i686 -O2, that should work on both amd/intel I hope

i've managed somehow to install the oracle-xe on the chroot and copy the files from there, since after 3 (r)emerges i wan't able to have the files installed.
then i've run the configure and i got this:

i think that i've found the problem, but i don't know how to fix it.
i've cat the init script (since after starting i wasn't getting listener or db) and executed the commands inside step by step and on the listener start i get this:

That looks like
a) a permission problem - try to su to oraclexe user if you haven't already.
b) ORACLE_SID might be incorrect

Now these are oracle configuration problems, so we are getting really off forum topics here.

i've tried it in the 32bit chroot, on an i586 and on a i686 and the only way to have it work was on opensuse 10.3 i586. :-(

that's a really annoying issue!!!! now i've understood why that package never got into portage.
i'll try the full 11 or 10g version and see if i can make it work.
the bas thing is that i only need some minor features, as the db and sqlplus for some training but it seems that i have to install the full 1.6GB package for that....
at least it has a native x64 arch. i'll let you know if i can make it work and in a positive case i'll post an ebuild in the bugzilla.
anyway, returning to the point this thread started from:
i'd like to remove the multilib from my amd64 system, since i've seen some minor issues with some package compilation and have 32bit chroot for those 32bit packages. i was wondering if it really is a good idea doing it. i'd have a lot of duplicated packages and should recompile the entire system. does it really worths?! and what 32bit apps are there to use that don't have a 64bit counterparts or don't work for 64bit?!
