Error message when trying to run phpmyadmin

I'm trying to set up phpmyadmin going against mysql/mariadb fork (newly installed). I get the following error message in php_errors.log:

[11-Feb-2013 23:50:12] PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mysql.so' - libmysqlclient.so.16: cannot open shared object file: No such file or directory in Unknown on line 0

Open in new window

I attempted to configure mysqli by adding the following line to /etc/php.ini:

extension=/usr/lib64/php/modules/mysqli.so

Open in new window

When I do an ldd on /usr/lib64/php/modules/mysql.so I get the following output:

Here are some of the details of my environment:

Is the client package installed?
says it can't find libmysqlclient.so.16

libmysqlclient.so.16 is in /usr/lib.

[ollie@localhost lib]$ pwd
/usr/lib
[ollie@localhost lib]$ ls libmy*
libmysqlclient.a            libmysqlclient_r.so.16      libmysqlclient.so.16

MariaDB client package is already installed:

look under lib and lib64 for that name
it should be a symlink pointing to the actual file

forethought

How are you installing phpMyAdmin, PHP and MySQL? Are you compiling, or are you installing via yum?

I installed phpMyAdmin by adding the EPEL repo package and then just installed it via yum and have had no problems on my CentOS 6.3 systems.
