Apache/mod_Perl works perfectly fine with ActiveState Perl - though there are some restrictions^*.

You need to either build it your self, or install a binary that someone else built for you. As far as I'm aware ActiveState do not provide mod_Perl via on their PPM Server. Randy Kobes does provide it on his "Theory" server, see Re: Adding CPAN Modules to Active State Perl for more details.

Once you configure PPM, you can install mod_Perl to for your copy of Apache pretty much like any other PPM intsall. Randy also has a nice selection of other modules not available from ActiveState, so it's well worth a look, even if you don't want mod_Perl.

*The main restriction is that with mod_Perl/AS Perl is that Apache is forced to serialise connections, so you can't call yourself via HTTP from a mod_Perl script. See also CGI.pm uploads under mod_Perl on WinNT for other surprises I found.

HTH....
