Are you sure you have only one libmysqlclient on your system?  Older  
Red Hattish Linuxen come with MySQL 3.23, so if that's still around,  
you could be getting symptoms like this.  There can be only one.

Also, if you've built MySQL from source, try installing the official  
RPMs from mysql.com instead.
