You can't except if you build these also as RPMs. And rebuild every other RPM which depends on those against the newly built RPMs. > And once installed (either by the Package Manager -- and by the > way, why are the apps it lists so out of date?), what's the best way to > update PHP and MySQL? CentOS is not and never was about the latest and greatest. CentOS is about having a stable set of packages which do *not* change over the lifetime of the product (with a few exceptions). Security fixes are backported into these versions.

Read up on CentOS and try to understand why we ship exactly that set of packages contained in any of the 4 available CentOS versions. If you find that not having the newest software available, CentOS might not be the correct distribution for you. If you want to have a stable set of packages supported for seven years(!), then stay with CentOS. Mixing CentOS packages and "stuff from the web" will not help with that. Ralph
