Path issues (among others...)

[TheDevilsJester]

I started with an x86 Gentoo Installation, it worked perfectly for the past year or more, not a single issue, rock solid.

I purchase an AMD64 MotherBoard/CPU and go for the AMD64 Gentoo. Now I am not an expert linux user, but I know my fair share. The Gentoo64 installation goes fairly smoothly (except for the fact that not a single gentoo cd has ever detected my network card, a thing that all pre packaged distros I have used have done just fine...), however it only took a month for this installation to die. My 32bit apps would start crashing before the even loaded up, many packages wouldnt compile, and I had a circular dependancy blocking issue with portage.

So I decided to start a fresh install, this one hasnt even lasted a day. Sound doesnt work properly, kdm stopped booting up automagically, it wont even find kdm or other apps like that when I type them in the console, I have to specify the exact path to the binary to execute it, I have to run dhcpcd again after boot even though its run during bootup (and is successfull), many apps wont compile, mozilla-firefox-bin (after I updated my profile) crashes when I load it up (although the emerged source version works just fine) and many of my apps are complaining about missing libs (that are not actually missing!). For example, trying to start k3b so I can burn a x86 version of gentoo (because bleeding edge isnt worth this), I get the following error:

Have a look into /etc/ld.conf, all paths to libraries should be listed there.

I dont have an /etc/ld.conf, I do however have an /etc/ld.so.conf which properly lists the paths to all my libs (among them is the kde and qt paths), I tried to copy this as /etc/ld.conf and nothing changed. ldconfig also doesnt help.
