It has never been so easy to get the source of Perl, with development history. I have managed to fix a few other vcp bugs and mirrored the perl repository from Perforce at activestate with svk.
Repository at svn://svn.clkao.org/perl/p4-trunk/
They will be kept synced daily. I'll see if perl.org is interested in hosting it once the new svk/svn::mirror are released.
