Apache RPM and SuSE

How do I extend the installed apache RPM that came bindled with SuSE? I am currently running SuSE 8.0 with Apache apache-1.3.23-73 Is there a source package that I can install and rebuild apache the way I want to? Or should I just dump the installed RPM and build it by hand from a tarball? Advice? Suggesttions? Thanks. Ahbaid.
