Automounter AMD with LDAP

Hello, I'm trying to install the AMD automounter with ldap support on a 
FreeBSD 5.2.1.
I downloaded the lastest sources of am-utils and i configured it.
When I want to make it, i have an error like this :
$make
make  all-recursive
Making all in libamu
make  all-am
/bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I..  
-I../include    -g -O2   -c
-o misc_rpc.lo `test -f 'misc_rpc.c' || echo './'`misc_rpc.c
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include -g -O2 -c misc_rpc.c -o 
misc_rpc.o

Did somebody successed in installing am-utils on a FreeBSD 5.2.1??
