I updated our Distutils from 1.0.2.pre to 1.0.2 and still get the same error. 
This sounds like a bug in Distutils to me. It seems that it automatically adds 

sys.prefix+'/include/python'+sys.version[:3] to the include directories, which 
works fine as long as your Python interpreter is installed under sys.prefix in 
which case config.h is really in sys.prefix+'/include/python'+sys.version[:3].

But I believe that it still is legal to install Python specifying 
sys.exec_prefix, in which case config.h is found in

	sys.exec_prefix+'/include/python'+sys.version[:3]
	
I checked with Sophie Coon (who has used Disutils previousely to build 
extensions here) and she confirmed that she had to add this directory explicitly 
using the setup.py file.

For PyOpenGL, we tried to add:

depInclude = sys.exec_prefix + '/include/python' + sys.version[:3]

and:

	   libraries = [('interface_util',
			 
{'sources':['src/interface_util/interface_util.c','src/interface_util/platform.c
'],
			  'include_dirs' : [depInclude]}),

but the directory still does not show up on the compilation line :(
