[petsc-users] configuring on OSX

[Brian Van Straalen]

I can attach the config log.  mpi breaks for yet other reasons so I was
trying to simplify things sufficiently.

if I put mpi back in and take the compiler choices out, I still end up with
failure on CPP.   It seems determined to look for "/lib/cpp" which is only
correct for linux.
