rc4, PostgreSQL-installer on WinXP: problems with plpython

1. Python as PL was greyed out an could not be installed again via the
installer - contrary to rc3, where PL/Python's installation was offered
and did work.

2. When trying to install plpythonu with creatlang, this was not
possible because of something like "error in python.dll: python23.dll
not fount"
On my system python23 was replaced with python24 some days ago.
Only when I copied python23.dll to c:/windows/system32, createlang
did create plpythonu.
It was not sufficient to copy python23.dll to
C:\Programme\PostgreSQL\8.0.0-rc4\lib

If PostgreSQL needs python23.dll, the installer should have it,
should copy it into C:\Programme\PostgreSQL\8.0.0-rc4\lib and
createlang.exe should first search it there.
Other programms as winide, and natlink, which too still use
python23.dll do indeed have there own copy with them and have it in
there own privat lib-directory.
