Today I stumbled on a project called PyGUI that depends on packages based  
on the platform.

   http://www.cosc.canterbury.ac.nz/greg.ewing/python_gui/

"""
MacOSX - requires PyObjC (tested with PyObjC-1.2)
Linux - requires pygtk (tested with pygtk-2.14.0 and Gtk+-2.14.7)
Windows - requires pywin32 (tested with pywin32-213) and ctypes (included  
with Python 2.5 and later)
"""

If we use setuptools' extras like syntax, this would be:

   extras_require={'platform=macosx': ['pyobjc'],
                   'platform=win32': ['pywin32', 'ctypes']
                   'platform=unix': ['pygtk']}
