Er - I've had this error in the past, but as far as I remember it is
always because I am somehow picking up a fragment of the wrong numpy
C-API.  Usual steps (delete site-packages/numpy maybe
site-packages/scipy, <numpy_svn>/build <scipy_svn>/build, rebuild and
install, then remove site-packages/nipy <nipy-dev>/build if necessary,
or all traces of inplace build, then try again?

See you,
