Problem to build gem mysql2

Hi,

I have installed OEL 5u8, ruby 1.9.3 p194 and MariaDB 5.5. When I trying
to build gem mysql2 I got the following error:

[[email protected]_prod_server ~]# ruby -v

What do I need to do in order to install the mysql2 gem?

Hey Johan,

Searching google for the first line of the error indicates that you are
probably using MySQL <5.0. Is this true? If so, update MySQL to >5.0.
