Posting this here in case anyone else runs into the same problem.
I ran into a problem recently where PS started crashing during launch. LIBGL was producing and error about not being able to load swrast. This occurred immediately after my Linux distribution (Mageia) pushed out several updates to various GL-related packages. I install the NVIDIA driver from their web site (instead of the Mageia package) and it compiles against the current kernel during installation. Apparently, it was still looking for the old GL packages and that was causing the crash. Uninstalling and reinstalling the driver made it compile with the new GL packages and everything works again.
