Comment (by cdavid):

 Ok, Would the following be accurate ?

 "Why numpy headers are installed using add_data_dir and not add_headers?

 To enable several versions of numpy to be installed at the same time, as
 well as to deal more easily with eggs.

 More precisely: add_data_dir install headers system-wide (e.g. in
 /usr/include/ on unix if /usr is the prefix for installation), whereas
 add_headers install the headers in package-specific location (for example
 somewhere in /usr/lib/python2.5/site-packages/numpy/). Installing the
 headers system-wide prevents multiple version of numpy to be installed at
 the same time, and that's why add_headers use is discouraged for
 numpy/scipy."

 I wanted to add a link to the FAQ, but I don't have an account for the
 main wiki.
