[petsc-dev] funny error on osx

[Dave May]

It looks like your aren't specifying to download an mpi implementation. So
on Mac it's presumably picking up the crap already installed on your
computer by apple. I've never found this works. I always request petsc
configure download openmpi. This works for me.
