Well, if you're going to distinguish between 'perl' and 'Perl', than the former is the binary, while the latter is the language. CPAN, Activestate and PM belong to neither. ;-)

However, when I say "part of perl" (you can't hear the difference between 'perl' and 'Perl'), I mean everything that comes in the tarball. So that includes 'strict.pm', the manual pages and the 'perlbug' program, but doesn't include the DBI and certainly not "the community".
