Slamd64 and Firefox

Hello,

I'm using Slamd64.

I just compile the kernel "linux-2.6.18" and everything was fine... I uninstalled ALSA (drivers, utils and libs) to reinstall them again (because it was not working). Now Audio is fine, but for some reason, when I want to run firefox (or thunderbird) I recieve this message:

Code:

firefox-bin: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory

some env. variables:
LD_LIBRARY_PATH="/usr/X11R6/lib64:/usr/X11R6/lib"
QTDIR="/usr/lib64/qt"

I reinstalled gtk (for 32 and 64 bits) with "slackpkg".

Gimp is running correctly...

Any Idea? (Thank you!)
