Comment (by mamoll):

 Modify lines 341-350 of _osx_support.py as follows:
 {{{
         for index in reversed(indices):
             try:
                 if compiler_so[index] == '-isysroot':
                     # Strip this argument and the next one:
                     del compiler_so[index:index+2]
                 else:
                     # It's '-isysroot/some/path' in one arg
                     del compiler_so[index:index+1]
             except ValueError:
                 break
 }}}
 The {{{reversed}}} call is the critical bit. This makes sure that the
 right thing happens when you have more than one {{{-isysroot}}} compiler
 flag.
