I would like to learn what I need to do to get the software to compile
on FreeBSD-5.  I guess the question is, what information do I need to
provide?  The software in question is OpenPBS (http://www.openpbs.org),
so it nothing proprietary.  There were a whole bunch of dependency
problems that I worked through manually and finally got to the point
of the kp_proc failure.  Here is a snippet of code that produces the
failure:

~~~~~~~~~~
static unsigned long cput_sum(pjob)
    job         *pjob;
{
        static  char            id[] = "cput_sum";
        int                     i;
        u_long                  cputime;
        int                     nps = 0;
                                                                                
        cputime = 0;
        for (i=0; i<nproc; i++) {
                struct kinfo_proc       *pp = &proc_tbl[i];
                                                                                
                if (!injob(pjob, sess_tbl[i]))
                        continue;
                                                                                
                nps++;
                cputime += tvk(pp->kp_proc.p_rtime);
                                                                                
                if (pp->kp_proc.p_ru == NULL) {
                        struct  pstats  ps;
			                                                                                                                                           
                        DBPRT(("%s: p_stats 0x%lx\n", id,
                                (u_long)pp->kp_proc.p_stats))
