|Subject:||Default core Perl on windows cannot open packages|
I don't know if you can fix this one here. On windows, using a default build of Perl with no additional extras from Vanilla Perl or ActivePerl, you can't open packages from CPAN. In the core Perl case, CPAN.pm uses tar and gunzip, both of which don't exist on Win32. Not sure how to solve this problem short of moving Compress::Zlib and Archive::Tar into the core... (and possibly one or two more). But I've left it here in case you have any ideas.
