The devel/bugzilla port has an explicit LIB_DEPENDS dependency on
libmysqlclient.so.10 from the mysql323-client port. However, bugzilla
will work fine with just about any version of MySQL.

Could just insert USE_MYSQL, but the bugzilla port only really needs
access to the perl DBD::Mysql modules and can depend on MySQL
implicitly through that port..
