Your Python installation appears to be broken. Find the site.py module that you 
are actually importing. I.e. from the numpy source directory:

   $ python2.7 -c "import site; print site.__file__"

This will tell you the site.pyc file that actually gets imported. Find the 
associated site.py file (it should be in the same directory) and check to see if 
it has USER_BASE defined. The filename should be

   /users/hp6/apps/python27/lib/python2.7/site.pyc

If it isn't, that may be the source of your problem.
