Comment(by rgommers):

 Numpy is easier to build then Scipy (it has no C++ or Fortran code) and
 has no hard dependencies. It will be much faster if you have ATLAS
 installed though. To run the tests for both numpy and scipy you need nose
 (apt-get python-nose).

 As described at http://scipy.org/Installing_SciPy/Linux, you can install
 the prerequisites for numpy/scipy with the following on Ubuntu:
 sudo apt-get install gcc g77 python-dev atlas3-base-dev
 Then it is just a matter of
 python setup.py install
 for numpy.

 For scipy you can do the same, but if you are going to do development I
 would recommend an in-place install, which is described at

 Then you can just modify functions in the source tree, and you'll see
 those changes on import.

 Finally, you can work from just the downloaded source as you tried, but it
 will quickly pay off to learn how to use git. Without a version control
 system you will have problems generating patches to contribute back.
