Andre, did you get any demo programs to work with the mpich2 port? I got an error that mpi_init wasn't called correctly again. When I disabled MPI but kept PETSc enabled, I get an error that a pointer is freed before allocated (stack trace points at Global Parameters KrylovSolver dying in the default Parameters copy constructor ... most values were optimized away so I stopped digging).
Switching over to using all MacPorts system could be better but for that super easy install the dmg would probably be easier to support. I stopped using the Apple gcc because I wanted to use openmp for some code. Of course I'm accustom to fine tuning my builds of software so unless there is a large need out there I wouldn't waste too many cycles on it. -- Andy On Fri, Oct 8, 2010 at 6:07 AM, Garth N.
