hi all, newbie to perl here..

we have perl 5.8.0 running on Linux here on our server. and i need to use the Win32::LoginName() function to retrieve the windows username thats running the perl process.. everyone's been telling me i need to get the "win32" module, but when i look on CPAN, i can't find any module thats called just "win32"... all of them have something after it like Win32::API, etc.. where can I download the win32 module so i can install it on our server? and how difficult is it to isntall it on Linux?
