[f2py] Re: 64-bit problems - 'undefined symbol'

[Alan Briolat]

Never mind, I fixed the problem - I was assuming that the Ubuntu dev's
wouldn't be stupid enough to ship a broken Numpy.  Once I had the same issue
on 32-bit I downloaded 1.1.0 from sourceforge and installed that, and
everything works fine on both platforms.
