Actually mysql 3 clients should work fine with mysql 4 servers. So if you rpm -i --replacefiles (rather than rpm -U) the mysql4 rpms, thus leaving both sets of the libraries intact, you may be able to run the new server without rebuilding any of the other packages.

You can, and we have on two RHES3 production machines -- because of all the interdependancies on the shared libs, it's easier to simply install all the client RPMs, untarball the 4.x server into a location and run the install scripts, etc. It will read your /etc/my.cnf and make the libs over in /var/lib/mysql and so forth - a few minor mods to the init.d mysql script and you're done.

This mixed mode has been running like a champ, no problems.
