[firedrake] new firedrake install on El Capitan

Hi All, I'm finally moving with the times and have upgraded my macbook to El Capitan with the intention of installing firedrake. I have got as far as running firedrake-install --global but it has stopped with the error: Traceback (most recent call last): File "firedrake-install", line 842, in <module> build_and_install_h5py() File "firedrake-install", line 565, in build_and_install_h5py raise InstallError("Unable to find installed PETSc when building h5py") __main__.InstallError: Unable to find installed PETSc when building h5py Any idea what's gone wrong? Thanks, Jemma
