pkg-config and Windows

Wed Mar 17 11:47:07 EDT 2010

I have a program that needs to be installed with setup.py. But there
is a problem when I am trying to install the program with setup.py in
Windows. When I try to install with
python setup.py install
it goes like this
C:\>python setup.py install
 running install
 running build
 running build_py
 running build_ext
 ERROR: Could not find pkg-config!
As you can see
the installation finishes with the error:
Could not find pkg-config!
Is there any way how to find out pkg-config in Windows?
or how to solve the problem?
Thanks
L.
