I've added an update to the OP explaining this.

Its not exactly more clear :) as my experience is to get apache binaries on win32 an then build mod_perl separately ...

So if you're talking about mod_perl, you can LoadModule perl_module path/to/mod_perl.so

On win32 you also have to LoadFile "/Path/to/your/Perl/bin/perl5x.dll"
