Python scipy.weave not working anymore

I wrote a script a few months ago using python. In this script I use weave. This script used to work, but I retried running my program today after a few month and it doesn't work anymore. I get this error:

USAGE: facedetect.py [--cascade <cascade_fn>] [--nested-cascade <cascade_fn>] [<video_source>]

The error states: cannot find -lpython27

this is how the folder looks like (which the program is using)

enter image description here

Some extra information: I have a 64 bit pc, running windows 7, python is 32 bit.

Recently my Path variable was cleared, though I've added the python path to it, maybe I need to add something here too ?

It is finding python27.lib (in the python folder) but is skipping it as incompatible most likely as it was built with Visual C++ and you are using gcc - You probably had a gcc build of python on your path - if so you need to add it back or set the linker path to include . i.e. the current directory.
