The atlas rpm is still really rough on the edges. Ideally, you should 
not need LD_LIBRARY_PATH, and I should update the loader (the software 
which looks for shared libraries when launchdng a program) cache, but if 
I make a mistake at this point, this has the potential to screw up the 
whole machine....

Could you give me more information on the AMD failure ? Are you using 64 
bits mode ?

This is planned, and I already took contact with them a few weeks ago, 
but I didn't have time to do it properly yet.
