You create and activate some simple mod_perl functionality, such as
a script to be parsed by mod_perl.

... most possibly because current web servers tend to disable that
kinds of information leaks. There's a directive in httpd.conf limiting
the amount of server information disclosed in response headers.

I'd guess this (/cgi-bin/ directory) is set to be executed using the
CGI mechanism, not via mod_perl. Thus the scripts are given a pure
CGI environment, not something spiced up with mod_perl.

Either by creating something parsed by mod_perl, or by turning on
mod_info for your server, and checking the loaded modules from there.
