(hoping this is the right way to submit updates for wiki pages.) from this page: http://wiki.centos.org/TipsAndTricks/YumAndRPM first, there's this line: yum --disable "*" --enable "rpmforge" list available i'm guessing that should be: yum --disablerepo "*" --enablerepo "rpmforge" list available also, near the bottom (Method B): "For CentOS-5 - A package for rpmdevtools does not seem to be available." actually, there's one in EPEL for 5.5, but i don't know if you're counting packages that come from EPEL. in any event, there's certainly an rpmdevtools package that's installable on 5.5. rday -- ======================================================================== Robert P.
