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