The very latest perl documentation can be retrieved by performing an rsync as described in perlhack e.g

rsync -avz rsync://ftp.linux.activestate.com/perl-current/ .
[download]

As that is the edge material (it ain't called bleadperl for nothin' ;). But I imagine it would be much more useful to translate the 5.8.0 docs as that's the current stable release and I believe quite a few areas of the perl documentation will, and have, been re-written for the next stable release 5.10, but it won't be seen in the wild for a while yet (only Hugo really knows when :).
