MPICH2 fails to build with clang because of a clang (and/or ld) bug with Xcode 4.5.1. Issue originally reported to homebrew in Homebrew/homebrew#15533, "fixed" by disabling shared libraries altogether in bcb64c7. - Add an `--enable-shared` option - Add a `fails_with :clang` when building shared libs - Upstream is aware of the issue, but has no workaround besides using `llvm-gcc` when building shared libs - MacPorts is using a similar workaround at this time. - Tested on 10.7.5 with Xcode 4.5.2 with and without `--enable-shared` Closes Homebrew/homebrew#16299.

Please be aware that installing this formula along with the `openmpi`

formula will cause neither MPI installation to work correctly as

both packages install their own versions of mpicc/mpicxx and mpirun.
