I didn't realize that Dreamhost was offering boxes with the Netscape 2.0 server on it. The box my account runs on has Apache.
As I indicated, what I had in mind was changing the path that Perl uses to search for modules. You know, like adding a directory located within my account so Perl could find any modules I might put there?
Someone else replied by email, though. Turns out SETENV works in .htaccess after all. I had previously been told that it HAD to go in httpd.conf (which is something I'd hope Dreamhost would be careful about letting customers screw with).
