Installing WSGIKit, opps I mean Python Paste under Win32

Ian has been unhappy with the name WSGIKit, so it has been renamed Python Paste I think the name better matches what the package does, the WSGI glue that sticks all the python components together. Anyway have made some minor changes to my cross-platform build-pkg.py script so that it works more like Ian's shell script. Have sent a copy to him, so who knows, maybe it will be part of Python Paste.

                                                                               
#!/usr/bin/env python
"""
Install required third party packages for Python Paste.

Known limitations

 - Running under Windows, it must be run with Python 2.3+
   as it requires the tarfile module. On Unix/Linix platform
   will fallback to tar program.
