[Zope] using Perl "inside" Zope

[Carl David]

After lots of hacking, I think I've got an old CGI.pm module and perl
program, renamed to a py extension and stored in /Extensions with a
correct first line pointing at the perl interpreter, and still it says
there is an error on the line "use CGI".
The program itself executes from the command line, outputs HTML code,
etc., to the screen, but inside Zope, its a big Nope.
Can someone explain to me what I'm doing wrong?
Thanks
