DragonFlyBSD

Hi I am trying out DragonFlyBSD and have missing pidfile_open when using mount.
I noticed this after building world from commit c24de52e9d066f36243cbe68aa1bbd9f7b423d02.
I am also running custom kernel - but the configuration is clone of the default X86_64_GENERIC without the parallel port

I replicated that situation using

/* pidfile_open.c */

#include <libutil.h>
#include <stdio.h>
#include <errno.h>
#include <string.h>

/* problem with linking at c24de52e9d066f36243cbe68aa1bbd9f7b423d02 */
int main( int argc, char **argv ) {
struct pidfh *retpid = pidfile_open("pidfile.xxx", 0600, NULL);
if(!retpid) {
printf("Error pidfile_open %s\n", strerror(errno));
}
return 0;
}

and linked it with

gcc pidfile_open_test.c -o pidfile_open -lutil

file links fine but when running I got
./pidfile_open
/tmp/pidfile_open: Undefined symbol "pidfile_open"

strangely ldd reports

ldd ./pidfile_open-x
./pidfile_open-x:
libutil.so.4 => /usr/lib/libutil.so.4 (0x80082b000)
libc.so.8 => /usr/lib/libc.so.8 (0x800a3c000)

and
readelf -a /usr/lib/libutil.so|grep pidfile_open
152: 0000000000007d75 848 FUNC GLOBAL DEFAULT 9 pidfile_open

what am I missing, or I did something wrong ?
