Python is installed in an "usr/" subdirectory of its own checkout. 
Now, the strange thing is:
- if I `cd` into usr and then run `bin/easy_install`, C extensions compile fine
- if I run directly `usr/bin/easy_install`, the headers are not found

Perhaps setuptools/distutils is confused by the fact that there is already a
Makefile (or a python executable) in the current directory?
