Build fails on 10.9.5 Mavericks

[vielmetti]

It went very far, but failed with this message:

==> python setup.py install --prefix=/usr/local/Cellar/gnuradio/3.7.5.1/libexec
               pdftops: no

============================================================================
                        * The following required packages can not be built:
                        * freetype

READ THIS: https://git.io/brew-troubleshooting
If reporting this issue please do so at (not Homebrew/homebrew):
  https://github.com/metacollin/homebrew-gnuradio/issues

but freetype is already installed:

edwards-air:~ emv$ brew install freetype
Warning: freetype-2.5.5 already installed

so I'm not sure what's going on; investigating.

The freetype issue seems to be related to

https://github.com/Homebrew/homebrew-python/issues/74

and perhaps fixed by
