[firedrake] Locally installed FFC not found on ARCHER

[Eike Mueller]

Dear firedrakers,

I need to install my own version of FFC, since the one already installed 
in /work/y07/y07/fdrake appears not to be compatible with the firedrake 
version I use:

RuntimeError: Incompatible Firedrake version 0.12.0 and FFC version unknown.

So I installed FFC locally and added it to PYTHONPATH:

/work/n02/n02/eike//git_workspace//firedrake-helmholtzsolver/source:/work/n02/n02/eike//git_workspace//firedrake-bench:/work/n02/n02/eike//git_workspace//pybench:/work/n02/n02/eike//git_workspace//firedrake:/work/n02/n02/eike//git_workspace//PyOP2:/work/n02/n02/eike//git_workspace//petsc4py/cray-gnu-shared/lib/python2.7/site-packages/:/work/n02/n02/eike//git_workspace//COFFEE/build/lib:/work/n02/n02/eike//git_workspace//ffc/build/lib.linux-x86_64-2.7/:/work/n02/n02/eike//Library:/work/y07/y07/fdrake/ufl/lib/python2.7/site-packages:/work/y07/y07/fdrake/scientificpython/lib/python2.7/site-packages:/work/y07/y07/fdrake/psutil/lib/python2.7/site-packages:/work/y07/y07/fdrake/mpi4py/lib/python2.7/site-packages:/work/y07/y07/fdrake/instant/lib/python2.7/site-packages:/work/y07/y07/fdrake/fiat/lib/python2.7/site-packages:/work/y07/y07/fdrake/ffc/lib/python2.7/site-packages:/work/y07/y07/fdrake/decorator-3.4.0/lib/python2.7/site-packages:/work/y07/y07/fdrake/petsc/arch-linux2-cxx-opt/lib/pyth

However, in python, the /work/y07/y07/fdrake version comes *first*, so 
it always picked up when I import ffc and I keep getting the error 
message above:

Any idea what is going on here? I can of course remove the unwanted FFC 
path, but there must be a more obvious solution.

Thanks a lot,
