I don't know why it or any other package "should" provide a binary
distribution for Windows, having one would be nice but shouldn't be a
hard requirement, ever.
This does point to an missing feature in distutils or setuptools
though: neither distutils nor setuptools has a way to specify the
supported platforms, at least not in a way that is actually used
during installation. It would be nice if the appscript author could
add some metadata to his setup.py file that would result in a clear
error-message when you try to install it on a platform other than
The only way to achieve that at the moment is to add some code to
setup.py that explicitly raises an exception when you try to build it
on an unsupported platform.
The same is true for the python version, pyobjc currently explicitly
tests for python >= 2.3,<3.0 because other versions aren't supported
and cause compile errors (at best, IIRC it will compile with python
2.2 but cause interpreter crashes when you try to use it).
