Dear Lawrence, Miklos, and Patrick,

Many thanks for your helpful suggestions. I have now successfully installed firedrake.
My guess is that certain compilers were not properly linked. brew doctor said that gcc
was not linked. But as I am a novice, my "guesses" mean little more than a child's 
comments on the newest navigation system of an A380.

Cheers,
Thomas

It sounds like your keg is not linked (sorry for the brew terminology). Does

$ brew link open-mpi

help? What does

$ brew doctor

say?

It appears that OSX has decided to put mpif90 in /usr/local/Cellar/open-mpi/1.10.2/bin/mpif90,
but the PETSc compilation is looking for it in /usr/local/bin/. Any idea why, or what we can
do?
