[firedrake] Locally installed FFC not found on ARCHER

[Eike Mueller]

Hi Michael,

I'm using quite a few non-standard branches 
(petsc->knepley/fix-plex-1d-refinement, PyOP2->columnwise_kernels, 
firedrake->multigrid-extrusion) to get my extruded multigrid working. 
The dependency on the non-default PETSc required me to install both this 
and petsc4py locally. I also installed FFC, UFL, FIAT and COFFEE 
locally, since the central versions were still out-out-of-date yesterday.

But to test your changes, I can try running a basic firedrake code and 
use the centrally installed firdrake version.

Just to be clear: You updated both PyOP2 and firdrake centrally, so in 
the instructions here 
https://github.com/firedrakeproject/firedrake-bench/wiki/Archer I do not 
need to build a local firedrake version and can leave out the following 
in firedrake.env and my jobscript:

export 
PYTHONPATH=$WORK/firedrake-bench:$WORK/pybench:$WORK/firedrake:$WORK/PyOP2:$PYTHONPATH

Thanks,

Eike
