[Koha] 2.2 printer settings page shown as plain text

[Jared Jennings]

i've got my 2.2 install up, and i'm poking around in the settings.
when i pick printers, i see HTML markup. it's filled out (no <!--
TMPL_* -->), and looks like it would make a pretty good printer
picking page; but i see the markup not the rendering. the z3950
settings (also in the /cgi-bin/koha/admin/ dir) work fine; the .tmpl
and the .pl for the printers have the same permissions as everything
else.

i haven't dug deeply into the printers.pl. it might be useful to know
i'm running on mod_perl.
