Use the --include (-I) option to "build_ext".

OK, sounds straightforward so far.

Yup, all working as planned.

D'ohh! Well, Distutils really can't figure this out automatically: it
can only presume that what it needs is installed to the standard Python
directories, and if you put stuff elsewhere, you'll have to tell it.
Luckily, this isn't hard. Instead of running just
python setup.py build
you would tack on some "build_ext" options to control how extensions are
python setup.py build build_ext -n -I/your/home/dir/include/python
Note that you can't use ~ here; only the "install" command expands ~ and
