Distutils doesn't provide a perfect solution, but if everyone just  
lets distutils put header files into the default location, and all  
packages get installed without an explicit prefix, then it will just  
work. Considering that I get next to no support questions about such  
installation issues, I consider the current situation very acceptable.

That's for numpy. How about Numeric and numarray? And how about  
whatever other packages need header files? If everyone makes up his  
own conventions, we end up with a big mess.


Another idea: considering that setup.py needs to be changed anyway to  
make eggs (because setup must be imported from somewhere else), why  
not put some flag "make_egg" at the beginning of numpy's setup.py,  
and depending on the value of the flag either use setuptools.setup  
and header files in the data section, or distutils.core.setup and  
header files in the standard location? That should suit everyone, right?
