To building on version >= 4.10 you have to patch configure:
+++ --- configure 2005-05-17 13:00:45 +0200 +++ configure.freebsd 2005-05-17 17:02:16 +0200 @@ -2404,7 +2404,7 @@ CFLAGS="$CFLAGS -DOS_SYSV -DDSO_DLFCN -Kthread" LDFLAGS="-Kthread $LDFLAGS -ldl" ;; - freebsd4.?) + freebsd*) CFLAGS="$CFLAGS -DOS_FREEBSD -DDSO_DLFCN -D_THREAD_SAFE -pthread" LDFLAGS="-pthread $LDFLAGS" supported_os="freebsd" +++
You also may have to set LD_LIBRARY_PATH and export it:
LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/i386/client:$JAVA_HOME/jre/lib/i386 export LD_LIBRARY_PATH
