[CIG-SHORT] Pylith 1.0.2 binary runtime error on Linux

Brad and Matt,

Thank you for your prompt response.  Brad, I ran the location checks below. My 
problem seems to be that "topologymodule.so" points to the (older) petsc-dev 
libraries I had installed in July.  So, the simplest thing I could think of was 
to create a script to clean up my paths of the petsc-dev libraries.  Pylith now 
runs without error and I can view the VTK files.

Looks like an alternative (and a more long-term solution) would be to update my 
petsc-dev as Matt suggested, and then I should be able to run without having to 
clean-up my paths.

Happy Holidays!
Ravi.
