[SciPy-user] inline.weave compile error

I am trying to compile some inline c++ code inside python using weave. I always get a similar problem where the compiled file cannot be found (See below output). I am not sure if the problem is with the compiler or something else. I am a new user of scipy and a novice with python so I would appreciate any direction someone can give me because I have not been able to figure out a work around.

Thank you,
Michael

I have the following related applications installed:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Python:
2.4.1 (I am using an older version because this is what ESRI GIS application  supports)
 
Scipy:
scipy-0.6.0.win32-py2.4.exe

MinGW:
MinGW-5.1.3.exe

OS:
Windows XP SP2

When I test the installation of Weave I get the following output:
