[AstroPy] OSX issues with the location of gfortran

[Jim Ramberg]

Hello:
    Recent  releases of OSX has gfortran being moved to the gcc package.  So
astropy tests that have a preset path for gfortran are failing

Here is one of the errors I see:

/Users/ramberg/astropy/docs/convolution/kernels.rst:304: UnexpectedException
__________________________________________________________________________
[doctest] index.rst
__________________________________________________________________________
023 Hubble constant at z=0 (i.e., ``H0``), and the number of transverse
proper
024 kpc corresponding to an arcminute at z=3::

032   >>> cosmo.kpc_proper_per_arcmin(3)  # doctest: +FLOAT_CMP
UNEXPECTED EXCEPTION:
ImportError('dlopen(/usr/local/lib/python2.7/site-packages/scipy/special/_uf
uncs.so, 2): Library not loaded:

Referenced from: 
/usr/local/lib/python2.7/site-packages/scipy/special/_ufuncs.so\n  Reason:
image not found',)
Traceback (most recent call last):



I was wondering if there is a workaround for this or should I just create a
symlink 
The correct location on my system is:
/usr/local/Cellar/gcc/4.8.3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/i386/l
ibgfortran.3.dylib

I am running osx mavericks.

Thanks
Jim
