No need to apologize.

That's one error I hadn't expected.  Which python do you use?   Are you using a prebuilt binary from the python.org website or something else? 

What's the output of this code:

:>>> import sysconfig
:>>> print sysconfig.get_config_var('USE_TOOLBOX_OBJECT_GLUE')

I'd expect that this prints None on your system, which is a configuration I haven't tested in a long while.

There are source archives for all bits of pyobjc on PyPI.  I don't have an archive with all of PyObjC at this time.

The setup.py file for 'pyobjc' itself contains a list of subprojects, if you install the source archives for the subprojects in the order they are listed there you should be able to install without an internet connection.
