Just for reference, you can find the build dependencies of any Debian
source package by looking at its .dsc file. For numpy, that can be found
at http://packages.debian.org/sid/python-numpy

Currently (version 1.1.0, debian version 1:1.1.0-3), that list is:

Build-Depends: cdbs (>= 0.4.43), python-all-dev, python-all-dbg,
python-central (>= 0.6), gfortran (>= 4:4.2), libblas-dev [!arm !m68k],
liblapack-dev [!arm !m68k], debhelper (>= 5.0.38), patchutils,
python-docutils, libfftw3-dev

Build-Conflicts: atlas3-base-dev, libatlas-3dnow-dev, libatlas-base-dev,
libatlas-headers, libatlas-sse-dev, libatlas-sse2-dev

Some of that stuff (cdbs, debhelper, patchutils) is specific to the
Debian build process and wouldn't be necessary for simply compiling
numpy itself.

And on a Debian (derivative) system, you can stall those with "apt-get
build-dep python-numpy". This will only install the build dependencies
for the version of python-numpy which is listed in your apt
sources.list, but 99% of the time, that should be sufficient.
