This is a problem with plugins. Unless the software/library is
prepared to use the lib64/lib32 path to the plugin it will allways use
the native bitness and fail if that is wrong. In this case libGL needs
to be patched to look in /usr/lib32/dri when compiled for 32bit and
/usr/lib64/dri when compiled for 64bit.

I'm reassigning this to libgl1-mesa-glx, the source package for libGL.

MFG,
