Yes, the problem is still there. I tried it on Hardy, Jaunty, Karmic,
and Lucid and they all fail with the same error message:

$ python -c "import dolfin"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/fenicsslave/jhbuildbot/fenics/lib/python2.6/site-packages/dolfin/__init__.py",

    import dolfin.cpp as cpp

ImportError: /usr/lib/openmpi/lib/openmpi/mca_paffinity_linux.so:

It worked fine when I comment it out on Mac.
