Installing 4.x inside a 5.x jail / chroot

I've been submitting a number of ports recently, mostly Perl-based ones.
Sometimes they don't work on old Perls (and Kris Kennaway has always
been there to inform me; shame that I couldn't respond before Simon
Barner did this morning). At the moment I don't have a 4.x machine
configured to run the six or seven year old 5.005_03 release that's in
the 4.x base system. This means that I can't (easily; switching the 4.x
box to use 5.005_03 is a mess and I've broken my installation that way)
test my ports before submitting them for systems running this ancient
(but still supported) version of Perl. I've been considering installing
RELENG_4 inside of a jail on my 5.x machine (the 4.x machine is too
starved for resources now as it is, I don't want to make its life any
harder), but I'm not sure how well that would work. Has anyone had any
experiences with this? Any caveats? Can I simply replicate the
instructions in jail(8) but with RELENG_4 bits? Thanks in advance.
