I would strongly recommend that you recompile the whole mess. Firstly, it's good experience. Secondly, you get to choose exactly what you want, and no more. mod_perl is a big enough pig as it is, without having modules that you'll never need compiled in as well.

When you do so, make sure you select the mod_info module. It's not included by default, and it will provide you with copious amounts of information as to what exactly is compiled into your binary.

update: you are also a couple of versions behind (which is SOP for canned distributions). Apache is sitting at 1.3.20 and mod_perl is 1.26. You really want to wean yourself off RPMs, .debs or whatever for critical applications such as web, dns and smtp. If a big security flaw comes up you want to be able to exercise the option of updating from a tarball directly, and not wait for some package maintainer to get around to bundling it up.
