配置Mysql 和FreeRadius出错，请高手指点？

stao

我配置Mysql和FreeRadius时，Radiusd -X 不能正常启动。
错误信息是
sql: group_membership_query = "SELECT GroupName FROM usergroup WHERE UserName='%{SQL-User-Name}'"
sql: connect_failure_retry_delay = 60
sql: simul_count_query = ""
sql: simul_verify_query = "SELECT RadAcctId, AcctSessionId, UserName, NASIPAddress, NASPortId, FramedIPAddress, CallingStationId, FramedProtocol FROM radacct WHERE UserName='%{SQL-User-Name}' AND AcctStopTime = 0"
rlm_sql (sql): Could not link driver rlm_sql_mysql: file not found
rlm_sql (sql): Make sure it (and all its dependent libraries!) are in the search path of your system's ld.
radiusd.conf[14]: sql: Module instantiation failed.
　我已经把/usr/local/lib 拷到了 usr/lib
   还是提示，和上面一样的错误，请高手指点

先直接登录一下MySQL看看是不是正常

stao

[root@STAOSVER /]# mysql -u root -p radius

已经解决，自己来回答了。不知道我理解的对不对，请各位大哥指点。
我在，我在编译FreeRadius前因为没有安装，MySQL-devel-standard-4.1.12-0.rhel3.i386.rpm ; 所以造成FreeRadius在编译时并没有把Mysql的模块编译。
所以当启动Radius时，才找不到Mysql的库文件。
