Have you a system other that DragonFly where you can test it?
So we can see whether it's DragonFly specific or not.

I got something similar when I tried to compile a Ruby extension with 
-pthread (see below). Maybe the same happens in your case.

Can you give the compilation output of your extension (ldap)?


The following is a mail to the FreeBSD maintainer of ruby18:

---
I don't know why, but my application raises an illegal instruction 
(signal 4) exception if it is linked with -pthread.
The problem now is that -pthread is always given, even if ruby18 is
compiled without WITH_PTHREADS. After I moved:

CFLAGS+=${PTHREAD_CFLAGS}       # Keep this, else ruby will fail to load
LDFLAGS+=${PTHREAD_LIBS}         # libraries dependent op libpthread.

into the .if defined(WITH_PTHREADS) section, it works nice! Is there
a reason it's not in this section?
