I hope I've fixed it for the next release I've added 
pkgconfig(mariadb-server) as a requirement and hopefully pkgconfig can 
sort it out. The choices were mysql-server, mysql-compat-server or 
mariadb-server. It now looks like mariadb-galera-server is gone from 
epel so the problem should be solved.
