BUG: port numpy should depend on python24

that is how it looked:

Hm. Got that solved by manually installing python24, but now I'm  
stuck at building scipy itself.

The first problem was in the setup script of one of the scipy  
modules. In scipy-0.5.2/Lib/odr/setup.py, Line 9 method "get_path" is  
imported from some numpy module, but that method doesn't exist there.  
Replacing

from numpy.distutils.misc_util import get_path, Configuration, dot_join

by

from numpy.distutils.misc_util import Configuration, dot_join

solves the issue. However, I don't know why it was imported because  
it is not used in Lib/odr/setup.py at all. This is how it looked:

Now, having that fixed, the next error seems to be a linking error.  
Obviously someone forgot to link against the Python Framework /  
libpython2.4.dylib. Linking happens to fail for every Fortran module,  
cluster and io on the other hand are built without error. Could  
someone shed light into this?
