yeah, I completely understand the unfortunate packaging situation (eg, some
of my packages do not work with this install method).

Here is a simple package requiring numpy.  It uses buildout (
http://www.buildout.org/).  To help easily reproduce the problem, here are
the commands to reproduce.

curl -O http://rene.f0o.com/~rene/numpy_buildout.tar.gz
#wget http://rene.f0o.com/~rene/numpy_buildout.tar.gz
tar xf numpy_buildout.tar.gz
cd numpy_buildout
python2.6 bootstrap.py
./bin/buildout


It prints out heaps of stuff... then finally fails with:

/var/folders/d1/d1p0zeCxF7Kz3G5FZJsh6E+++TM/-Tmp-/easy_install-2WsZVp/numpy-1.3.0/numpy/distutils/misc_util.py:219:

I hope that helps if someone wants to reproduce the problem very easily some
time.


notes:
* you should not have numpy installed already to reproduce the problem,
otherwise the buildout uses the installed version and works.
* use `python bootstrap.py -d` if you want to use distribute instead of
setuptools (which has python3.1 support).
* numpy with buildout works ok with python2.5



cheers,
