S Wood is still having a problem:
I compiled dolfin with no errors but when I try running the demos using
python I get a strange error:

$ python demo.py

Traceback (most recent call last):
  File "demo.py", line 22, in <module>
    from dolfin import *
  File "/usr/local/lib/python2.6/site-packages/dolfin/__init__.py", line 13, in <module>
    import dolfin.cpp as cpp
  File "/usr/local/lib/python2.6/site-packages/dolfin/cpp.py", line 28, in <module>
    _cpp = swig_import_helper()
  File "/usr/local/lib/python2.6/site-packages/dolfin/cpp.py", line 24, in swig_import_helper
    _mod = imp.load_module('_cpp', fp, pathname, description)

I did't notice any problem with swig during the installation. 

Here is my $PYTHONPATH:
/usr/local/lib/python2.6/site-packages:/usr/local/lib/python2.6/site-packages:/usr/local/bin:/root/Work/FEniCS/lib/python2.6/site-packages

And in response to:

ldd /home/user/Work/Codes/FEniCS/dolfin-0.9.9/dolfin/libdolfin.so.0

I get:
