what module is the windows message box in?

Hello,

I have a barebones release of Perl 5.8.  I need to use Win32::MsgBox
in the body of the script.  From CPAN I downloaded libwin32-0.191.zip
and installed it.  The problem is installing that module loads all the
Win libraries.  I only need to use the MsgBox and nothing else.

By themselves, I tried getting just Win32::OLE and that doesn't appear
to have MsgBox in it and I couldn't get Win23::GUI to build at all!

Is there a more abbreviated module I can get or is the entire
collection of Windows libraries as "low" as I can go?

Thanks,
