I got port xemacs-devel to build and run.  There are two bugs:

1. An rlimit value is stored 32-bit int, truncating the value
   and confusing the allocator.  This is in the xemacs sources.

2. unexelf.c was only using 32 bit things instead of 64.
   In this case it is the FreeBSD ports patch file that actually
   needs to change (these lines aren't present at all in the
   xemacs distribution).

The second change should instead be something like

    #if sizeof(char *) == 8

or some such.
