Comment(by rgommers):

 To get past the first error we can change the first part of
 {{{get_path_from_frame}}} to:
 {{{
     try:
         caller_file = eval('__file__', frame.f_globals, frame.f_locals)
         d = os.path.dirname(os.path.abspath(caller_file))
         # Ugly hack to support PIP install in a virtualenv.
         if d.endswith('build/numpy'):
             d = d + 'build/numpy'
 }}}

 Then we run into what looks like a pip issue:
 {{{
 running egg_info

 Running from numpy source directory.error: error in 'egg_base' option:
 'pip-egg-info' does not exist or is not a directory

 ----------------------------------------
 Command python setup.py egg_info failed with error code 1
 Storing complete log in /Users/rgommers/.pip/pip.log
 }}}
 this comes from {{{run_egg_info}}} in pip/req.py
