Which again points to problems with sysconfig.getconfigvar("CONFIGARGS"):

[The earlier call was with "__CONFIG_ARGS", for whatever difference that makes.] It appears to be returning None instead of [] (or a populated list).

In 3.2.2, at line 579 of sysconfig.py is def get_config_var(name): return get_config_vars().get(name)

That defaults to None if name is not a key in the dict returned by get_config_vars(). 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 "CONFIG_ARGS" 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 get_config_var(*args): global _CONFIG_VARS if _CONFIG_VARS is None: _CONFIG_VARS = {} <code to populate _CONFIG_VARS, including> if os.name in ('nt', 'os2'): _init_non_posix(_CONFIG_VARS) if args: vals = [] for name in args: vals.append(_CONFIG_VARS.get(name)) return vals else: return _CONFIG_VARS

At 456 is def _init_non_posix(vars): """Initialize the module as appropriate for NT""" # set basic install directories ...

"CONFIG_ARGS" is not set explicitly for any system anywhere in the file, so I do not know how the call ever works.
