Issue 1:
Hi all,

I've been trying to install scikit-learn on my GNU/Linux machine. I downloaded the tarball of the 0.14.1 source code and was able to complete "python setup.py build" and "python setup.py install" ok (well, they looked to complete ok!). However, as I go through the build tests, I get the following errors:

======================================================================
