Ok, that begins to show something:

    $ python -c "import xml.parsers.expat"
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/usr/lib/python2.7/xml/parsers/expat.py", line 4, in <module>
        from pyexpat import *
    ImportError: /usr/lib/python2.7/lib-dynload/pyexpat.so: undefined symbol: XML_SetHashSalt

Thats serious!

    $ python -c "import sys ; print sys.path"
    ['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk',

Nothing too strange there.
