It's looks like epics base is installed in
/Users/jamesbryant/Desktop/base-3.14.12.2.   You might want to consder
moving that to a more "installed" place, say
/usr/local/epics/base-3.14.12.2/ or even
/Users/jamesbryant/local/epics/base-3.14.12.2/.

But it looks like your real question is about installing the pyepics
interface to Epics Channel Access.   For that, now that you have Epics
base installed, download
http://cars9.uchicago.edu/software/python/pyepics3/src/pyepics-3.2.1.tar.gz
  then unpack that and run python setup.py from there:
   %> tar xzf pyepics-3.2.1.tar.gz
   %> cd pyepics-3.2.1
   %> python setup.py build

If you have EPICS_BASE set to point to your Epics base-3.14.12.2
directory, the setup.py should pick that up and let you know whether
or not it found the CA library (libca.dylib on OSX).  If all goes
well, you can then install this with

   %> sudo python setup.py install

Hope that helps,
