[firedrake] FD on mac

Onno, that's strange. Are you sure you followed my instructions correctly?
Because simply reinstalling Homebrew is not going to fix the fortran issue.
You need to manually reconfigure openmpi to use the latest gcc
compilers. First ensure you have the latest gcc via Homebrew (I think it
should be gcc-5). Then you "install" openmpi initially (via brew install
openmpi). Finally you need to rebuild openmpi via

brew reinstall openmpi --build-from-source

Because by default, the openmpi links to the apple compilers, and for some
reason mpif90 is not hooked up to any gfortran. Hence you need those
environment variables I stated.

They do something similar here
http://stackoverflow.com/questions/26812780/linking-homebrew-compiled-openmpi-or-mpich2-to-homebrews-gcc

This should fix that fortran problem within the PETSc build process.

Spatialindex needs to be rebuilt the same way.

Thanks,
Justin
