Delete the numpy/ directory in site-packages/ and delete the f2py

Don't worry about these. In order to figure out if your system
supports certain features, we try to compile and execute a number of
small C programs. If the compilation fails, then your system doesn't
support that feature; that's fine, we just make the appropriate

Don't bother for either numpy or scipy.
