You can just throw on the perl executable for whatever
system you are using. It will easily fit on a zip disk,
and the unix system version will *easily* fit on a
zip disk. Just copy it over and add it to your path.
If you are using some other system (e.g. Win9x) it is a
little more complicated, but it that case I'd just throw
the whole Perl installer on the zip disk and install it
to the machine you are using. Or just ask the sysadmin
to install it - the whole \PERL subdirectory is only
about 12 Meg, as I recall.
