[Zope-Perl] building pyperl on Windows

[Chris McDonough]

Hi Gisle,

The build routine for pyperl-1.0 beta 6 includes a script
"Python-Object/pyinc.py"

It seems that you figure out the system dir (when running perl Makefile.PL)
by using sys.prefix in this script.

Unfortunately, it seems on Windows that sys.prefix is the blank string (at
least on my binary install of Python 1.52.).

A workaround is as follows:

if sys.platform == 'win32':
 import site
 place = site.__file__[:-12]
 print os.path.dirname(place) + "\\Include"
else:
 print os.path.join(sys.prefix, 'include', 'python' + sys.version[:3])
