[with patch, positive review] new scipy-0.7.p2 spkg is broken on 64-bit OS X, due to numpy

[William Stein]

To replicate this on OS X:

1. export SAGE64="yes"
2. Try to build Sage, which will fail because of Fortran
3. install the experimental fortran spkg:

   sage -i fortran-OSX64-20090120
   

4. fix ratpoints using the spkg in #6492
5. continue the build and get the following error. Note that scipy used to work, for sage-4.0. So something got messed up when we ugpraded scipy.

It turns out this is caused by a bug in numpy :-). I commented out the not-needed line that is patched here ​http://projects.scipy.org/numpy/ticket/1087 and the build completes fine. So here is a new numpy spkg.

With this package and the patched ratpoints, sage builds completely 64-bit on OS X.

I'm renaming this spkg to numpy-1.3.0.p1.spkg since there is already an spkg called numpy-1.3.0.p0.spkg in Sage 4.1. This is to prevent confusion later on: people might wonder why Sage 4.1 and (the upcoming) Sage 4.1.1 each has a numpy spkg with the same name as each other, but patched differently. The renamed spkg is up at
