<p>I want to use Apple's or RedHat's built-in Apache but I want to use Perl 5.10 and mod_perl.  What's the least intrusive way to accomplish this?  I want the advantage of free security patching for the vendor's Apache, dav, php, etc., but I care a lot about which version of Perl I use and what's in my @INC path.  I don't mind compiling my own mod_perl.</p>

You'll want to look into
mod_so
