In 3.2.2, at line 579 of sysconfig.py is def getconfigvar(name): return getconfigvars().get(name) That defaults to None if name is not a key in the dict returned by getconfigvars(). My guess is that it always is and and the the value is always a list for tested win/*nix/mac systems. So either setup.py has the bug of assuming that there is always a list value for "CONFIGARGS" or sysconfig.py has the bug of not setting it for os2, perhaps because of a bug elsewhere. At line 440 of sysconfig.py is def getconfigvar(*args): global CONFIGVARS if CONFIGVARS is None: CONFIGVARS = {} <code to populate CONFIGVARS, including> if os.name in ('nt', 'os2'): initnonposix(CONFIGVARS) if args: vals = [] for name in args: vals.append(CONFIGVARS.get(name)) return vals else: return CONFIGVARS At 456 is def initnonposix(vars): """Initialize the module as appropriate for NT""" # set basic install directories ... "CONFIGARGS" is not set explicitly for any system anywhere in the file, so I do not know how the call ever works. This looks pretty much the same as the code in 2.7.2 - I don't understand Python code well enough to debug the script :(

Thanks for the response,

Paul
