Exactly how did you install numpy? Did you use easy_install? What does
the egg directory look like? For example inside my egg, there is a
subdirectory called EGG-INFO/ which has another subdirectory called
scripts/ which has the actual f2py script.

[scripts]$ pwd
[scripts]$ ls

This is what the bootstrap script installed to /Library/.../bin/f2py
is looking for.

If you did not intend to install an egg of numpy, this might be a
leftover from a previous try. Delete the /Library/.../bin/f2py script
and install numpy again.
