[OpenSER-Users] Failed to compile openser with freeradius support

HI, In FreeBSD 6.2, I got this error when I compiled openser with freeradius support. ../../radius.h:36:32: freeradius-client.h: No such file or directory acc.c: In function `init_acc_rad': acc.c:464: warning: assignment makes pointer from integer without a cast acc.c:475: error: `DICT_ATTR' undeclared (first use in this function) acc.c:475: error: (Each undeclared identifier is reported only once acc.c:475: error: for each function it appears in.) acc.c:475: error: `da' undeclared (first use in this function) acc.c:475: error: `DICT_VALUE' undeclared (first use in this function) acc.c:475: error: `dv' undeclared (first use in this function) acc.c: In function `acc_rad_request': acc.c:509: error: `VALUE_PAIR' undeclared (first use in this function) acc.c:514: error: invalid lvalue in assignment acc.c:555: error: `OK_RC' undeclared (first use in this function) gmake[1]: *** [acc.o] Error 1 gmake[1]: Leaving directory `/usr/ports/net/openser/work/openser-1.2.2-tls/modules/acc' gmake: *** [modules] Error 2 *** Error code 2 Stop in /usr/ports/net/openser. *** Error code 1 Is there any way I can compile openser with freeradius support?
