[firedrake] Locally installed FFC not found on ARCHER

[Michael Lange]

Hi Eike,

I just updated the "firedrake" module on Archer and it should be fully 
functional again. Can you please give this a try and let me know if it 
works for you?

The PETSc problem was due to fdrake-build-env pointing at a very old 
petsc build (petsc/dev), not the one Florian re-built yesterday 
(petsc/shared). I also pulled the entire mapdes stack forward, so we 
should be up-to-date with current master versions.

Also, as a heads up, I am currently working with Tim Bond and Rupert 
Nash from EPCC on rolling out separate petsc-master and petsc4py-master 
packages that use the centrally installed (and supported) Python stack. 
This is possible after several updates to the Python environment on 
Archer and should allow us to get off the relatively unsupported 
Anaconda module to avoid more binary incompatibilities in the future. 
I'll post to the list once we're ready to switch.

Thanks,
Michael
