Secure HTTP user CGI?

Greetings from a newbie. Just got RedHat 8.0. Once the host is up on the
network, I'll be signing up for support.

In the meantime, could someone please point me to a reference that will 
tell me how to set-up our HTTP users so they can each write their own
custom-written CGI, using Perl and Shell scripts, yet keep them from
accesssing files outside their own 'sandbox' (for example a chroot
'jail'). The problem is, how to make Perl binaries available inside the
sandbox without opening up the whole system, or copying Perl into every
sandbox......

Tips or pointers to docs would be much appreciated.
