Great!

This is a long lasting issue and several solutions have been proposed, see
scipy mailing archives.

The current solution for package installation of scipy,f2py,etc
would be the following:

1) Get scipy,f2py and their dependencies from CVS:

  export CVSROOT=:pserver:anonymous at scipy.org:/home/cvsroot
  cvs co scipy_core
  cvs co -d scipy world/scipy

  export CVSROOT=:pserver:anonymous at cens.ioc.ee:/home/cvs
  cvs co f2py2e

2) Disable chaco (for simplicity), scipy_core packages in
scipy/setup.py file by commenting out the following lines:

  separate_packages += core_packages
  separate_packages += chaco_packages

3) Disable scipy_distutils checkout in f2py2e/setup.py file by replacing
the line

  if 'sdist' in sys.argv and not os.path.exists('other/scipy_distutils'):

with

  if 0:

4) Create source tar-balls

  cd scipy_core
  python setup.py sdist
  cp dist/Scipy_core-*.tar.gz ..
  cd ..

  cd f2py2e
  cp dist/F2PY-*.tar.gz ..
  cd ..

  cd scipy
  python setup.py sdist
  cp dist/SciPy-*.tar.gz ..
  cd ..

5) Install scipy_core, f2py2e, scipy in the given order (now there are no 
overlaps in software installations):

  Unpack tar-ball sources.

  cd Scipy_core-*
  python setup.py install
  cd ..

  cd F2PY-*
  python setup.py install
  cd ..

  cd SciPy-*
  python setup.py install
  cd ..

Let us know if such an approach is acceptable for debianizing scipy,f2py
then we can consider simplifying steps 1-3).
Other suggestions are welcome.
