What versions of python do you have installed, maybee more crucial what 
version of python were your PyDOLFIN compiled against?

What does,

   pkg-config --modversion python-2

tell you? This should be the version your PyDOLFIN installation is compiled 
against. It looks like your installation at least resides in python2.5, these 
versions needs to be the same.
