It does seem like it might be a mess related to having two numpy
installed: the local one, and the system one. It seems that during
compilation of nipy, numpy.distutils picks up the wrong header, that is
the system ones, and not those of my local instal of numpy (I tried with
a 'develop' and with an 'install').

When I compile nipy, the compile options are:

compile options: '-DATLAS_INFO="\"3.6.0\"" -I/usr/include
-I/home/varoquau/usr/lib/python2.6/site-packages/numpy/core/include
-I/home/varoquau/dev/nipy-neurospin/libcstat/fff
-I/home/varoquau/dev/nipy-neurospin/libcstat/randomkit
-I/home/varoquau/dev/nipy-neurospin/libcstat/wrapper
-I/home/varoquau/usr/lib/python2.6/site-packages/numpy/core/include
-I/usr/include -I/usr/include/python2.6 -c'

In /usr/include, there is (under ubuntu Karmic) a numpy directory, with
the numpy headers, corresponding to the system numpy.

I don't want to remove these headers, as that would mean removing the
python-numpy package on which many other packages depend.

Does anybody have a suggestion on how to cleanly solve the problem? I
fear I won't be the only one to have it.
