Installing to pfsense

Hi, I have currently installed freeradius 2.1.10 and Mysql 5..5.10 on a pfsense box which is freebsd. I want this to work with mysql however I was wondering how to install freeradius with mysql support as I am unable to do it via ports or try any commands or flags with ./configure via tarball. Only pkg_add is available, can I recompile or install from scratch to get freeradius to bind to mysql? Thanks, Frank
