[Numpy-discussion] Obscure setup question

[gvermeul at labs.polycnrs-gre.fr]

Hi,

This is very strange. I am also making packages (RPMs in my case).
I do this as a normal user without write access to /usr/.....

If running setup.py would have as a consequence that 
/usr/lib/....../install_headers.pyc would get overwritten,
then setup.py would die.

Can you tell if your python-2.1 is really 2.1 or 2.1.1?
It happens that I am tweaking the setup.py script of
Numeric and testing with python-2.1.1 and I am sure
that distutils works.

I suggest the following test:

login as a normal user, unpack Numeric, cd Numeric and do

python2.1 setup.py install --root=~/tmp

This will install Numeric in ~/tmp/usr/lib/python2.1 and
you will see if setup.py still tries to overwrite
install_headers.pyc

If so, your python2.1 is broken for some reason, if not
your build system and/or sandbox are broken.
