You may have already figured this out, but at least in certain configurations mod_perl 1.16 causes several errors in redhat SWS. The most noticable symptom is that CGI programs fail to work. Upgrading mod_perl to 1.16_02 fixes the problem. I created a new rpm by dropping the mod_perl 1.16_02 tarball into SOURCES and slightly editing the spec file. Sorry for the lack of debug info: there's not much to show but the fix.
mod_perl 1.16 is definitely broken, as you have determined. A new mod perl 1.18 will be released when we put out an update of perl5, which should be any day now. It fixes this CGI execution problem.
