How to run f2py in macosx
Question: Hi I am trying to use f2py in macosx.  
I have a homebrew python instalation and I have installed numpy using pip.  
If I write on terminal `f2py` I get `-bash: f2py: command not found` but if I
write in a python script `import numpy.f2py`it works well. How can I solve
this problem runing f2py directly from terminal? Thank you!


Answer: I had a similar problem (installed numpy with pip on macosx, but got f2py not
found). In my case f2py was indeed in a location on my $PATH
(/Users/_username_ /Library/Python/2.7/bin), but had no execute permissions
set. Once that was fixed all was fine.
