kerberos library problems after portage update

Hi

After I did an 'emerge portage' kerberos was updated. Now many things are broken. For example Pine and Xscreensaver would not work until I did 'ln -s /usr/lib/libkrb5.so /usr/lib/libkrb4.so.2'. Now Pine will work but xscreensaver will not work and will not recompile (even the most recent version) with or without the link.

regards

I too have this (only very recently). I solved xscreensaver by rebuilding, but others (E.g. pure-ftpd) are not so successful.

I did have kerberos in my use vars, I've taken it out now, but still no joy.

Has anyone got any ideas? I've re-emerged kth-krb, mit-krb5, and pam-krb5, but still no joy.
(Yes, only kth-krb is a kerberos 4 implementation; I'm clutching at straws here)

I also am seeing this problem. I am working on the xscreensaver problem but I have yet to have any sucess. I even tried "USE=" " emerge xscreensaver" and the build died also.

I had the same problem too, just using xscreensaver. It's seems like the xscreensaver configure script assumes that if kerberos is installed on the system, the user must have both krb4 and krb5 libraries. I found a solution, but it's really a kludge and it only works for xscreensaver. Other apps might have a similar solution, though. The best solution is for these apps to have the authors fix the configure files.

Some of these steps may not be necessary if you have already done them once. This is more of a general outline for creating your own modified ebuilds to override those in portage. I did this also for creating a gentoo kernel with a modified set of patches.

Do these steps as root.

1) Enable the portage overlay directory. In /etc/make.conf, comment out this line:

You can get libkrb4.so etc by adding krb4 to your USE list and re emerging mit-krb5. This builds krb4 support within krb5.

I am not an expert. As a matter of fact, I had the same problem as you until I started poking around this morning. But one way is to look for the IUSE variable in the ebuild file.

For example:
/usr/portage/app-crypt/mit-krb5/mit-krb5-1.2.8.ebuild

has the line
IUSE="krb4 static"

these are the optional USEs it will look for.

You can also look at the USE variable guide int the docs section. It has a link to all the possible USEs. If you want extreme details, you can look at the Ebuild howto.

FYI, the newest ebuild of xscreensaver checks for the presence of both kerberos AND krb4 when including kerberos support so everything works together.
