Why don certain standard library modules work?
With ActivePerl, almost all modules will work with ActivePerl as long as they can be built to run on Win32. The problems that existed with the 3xx versions of Perl for Win32 no longer exist: modules work on Win32, not just this port or that port of Perl for the Win32 platform! If a module doesn’t work, it may be because the functions it uses are specific to UNIX and won’t work on Win32, or specific to NT and won’t work on Windows 95 or Windows 98.
