Actually, it turns out that NetBSD *does* have it also.

resource.h:
  #define RLIMIT_AS    10         /* virtual process size (inclusive of mmap) */
  #define RLIMIT_VMEM  RLIMIT_AS  /* common alias */
    
OpenBSD seems to be the only one that does not have it.

By the way, FreeSWITCH is not in pkgsrc.  I was trying to compile it
natively.  However, the RLIMIT_AS issue was not the only one.  Every
time I fixed one problem there was another.  Apparently it is very Linux
centric.  I don't have a lot of time to work on it so I gave up for now
and am going to take a closer look at yate.

Thanks for following up on this.  It is looking to me like RLIMIT_AS is (or is
becoming?) more of the standard and RLIMIT_VMEM is BSD specific.  I do not
see any mention of RLIMIT_VMEM in the posix specifications and Linux does not
seem to support it either.  At least it did not show up when I grep'd the
Linux headers under /archive/Linux-2.6.13.1 on leaf for it.
