I wasn't sourcing the correct file before.

I'm getting a ton of these now when I compile the Poisson demo:

/home/logg/scratch/lib/fenics-dev/lib/libpytrilinos.so: undefined
reference to `PyObject_SetAttrString'
/home/logg/scratch/lib/fenics-dev/lib/libpytrilinos.so: undefined
reference to `PyType_IsSubtype'
/home/logg/scratch/lib/fenics-dev/lib/libpytrilinos.so: undefined
reference to `PyErr_Fetch'
/home/logg/scratch/lib/fenics-dev/lib/libpytrilinos.so: undefined
reference to `PyCObject_Import'
/home/logg/scratch/lib/fenics-dev/lib/libpytrilinos.so: undefined
reference to `PyExc_RuntimeError'

Any ideas? I have never really used Trilinos before so I'm not
familiar with how it's setup, but do we really use the Python wrappers
for Trilinos? Perhaps they can be disabled in the build to get around
this.
