Initial Setup Troubles for Windows

[Clint Anderson]

Hey guys, I'm new to gnustep and am having some initial problems
getting it set up to play around with some Objective C dev in Windows.
 I have downloaded and installed both the core and the system files
from http://wwwmain.gnustep.org/experience/Windows.html.  I also had
previously installed mingw by itself.

I was trying to go through this tutorial,
http://www.techotopia.com/index.php/Installing_and_using_GNUstep_and_Objective-C_on_Windows
to test out a simple hello world but get this error when I  try to
compile:

 hello.m:1:34: fatal error: Foundation/Foundation.h: No such file or
directory compilation terminated.


Any tips on what parts of the setup I might have missed?

Thanks.
