pip version uses obsolete fortran library; update to match repo version?

[jamesdj]

I tried installing the library via pip, and was unable to use it because of the absence of the gfortran 3 library. Apparently this library is no longer supported on most operating systems. Cloning the repo and installing with setup.py install worked; as noted in the documentation, the current repo version uses gfortran 4.4.7. Could the glmnet-python version available via pip be updated to match the version in the repo?
