I think the RPMs have interdependencies that would prevent that, although you could try it. My advice is to get your 8.1.* RPMs from Fedora 5 rather than PGDG. Your "web server" options look like Red Hat's standard build environment, so the Fedora RPMs should have those same build options or close enough. And there's no difference worth noticing other than the Red Hat-ish build options, unless Devrim or I screwed up ;-) If the Fedora 5 RPMs won't install on your FC4 machine, grab the FC5 SRPM and do a quick rpmbuild --rebuild to make custom RPMs for your environment. regards, tom lane
