 Since the configure in python 2.7.12 doesn't have fine enough control to
 eliminate the usage of the poll() calls, I resorted to...

 {{{
                 perl -pi -e 's|\#define HAVE_POLL 1||' ./pyconfig.h
                 perl -pi -e 's|\#define HAVE_POLL_H 1||g' ./pyconfig.h
                 perl -pi -e 's|\#define HAVE_SYS_POLL_H 1||g' ./pyconfig.h

 post-configure which allowed fink's python27 package to successfully pass
 'make check'. MacPorts will need similar hack for the 10.12 python package
 builds.

Comment:

 This only affects python27, or also older and newer versions of python?
