Gael, orthogonal to reporting this to Ubuntu, I think you can do what
David suggests by configuring your variables correctly.

I have a pretty strictly manipulated set of valid installation $PREFIX
location, all of which I can use for

./configure --prefix=$PREFIX


./setup.py install --prefix=$PREFIX

and that's because for each one of these, I correctly configure ALL of these:

PATH: binary execution
LD_LIBRARY_PATH: dynamic linker search path
LIBRARY_PATH: static linking by gcc (like -L)
CPATH: generic include path for gcc (like -I), used for all languages
C_INCLUDE_PATH: C-specific include path, after CPATH
CPLUS_INCLUDE_PATH: C++-specific include path, after CPATH
PYTHONPATH: search path for python packages

I have some bash code to do this automatically, I can send it your way
if you want.

This doesn't out of the box work for in-place installs, because it
creates pythonpath with pythonX.Y/site-packages, so it would not cover
your in-place headers.  But you could easily use the utilities in
there to configure some of the *PATH variables with the location of
your numpy source tree, so the in-place installs work as you expect

I haven't tested it, but I think it should work.
