Ok, the problem was MySQL's RPM's. So, here is the solution: if you upgrade a system with glibc < 2.2 using the RPM's downloaded from MySQL.com, you may run into problems with PHP, *even* if the RPM's didn't complain about broken dependencies when they were rpm -F'ed and *even* if you compiled PHP without errors. The solution is to download the source RPM and rebuild the binaries, the upgrade MySQL from your built binaries and then recompile PHP, and you should be done.
Hope this helps someone else. -- PHP Install Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
