The Mac is running all the demos without problems.

The 32-bit machine was giving errors for 12 Python demos. After updating 
SWIG from 1.3.31 to 1.3.36, there is only a single demo failing, which 
is the same as discussed earlier for the 64-bit machine (PETSc error).

The SWIG error looked liked this:
Traceback (most recent call last):
  File "./demo.py", line 42, in <module>
    bc = DirichletBC(V, u0, DirichletBoundary())
  File 
"/home/buildbot/local/tmp/lib/python2.5/site-packages/dolfin/cpp.py", 
line 10342, in __init__
    this = _cpp.new_DirichletBC(*args)
TypeError: Swig director type mismatch in output value of type 'bool'

Is there an overview over what versions DOLFIN depends on somewhere? I 
remember earlier questions about Python, numpy and MPIP versions. I am 
not sure which SWIG version would be the minimum now, but I think it is 
1.3.33 as that is the version the 64-bit buildbot is using.
