Sorry for belated reply: I am not subscribed to the list, and for some
strange reason your reply went to the list only...

It turned out that the problem was due to overly aggressive patching of
src/Makefile in JtR FreeBSD's port.  After I realized that the problem
does not exhibit itself with vanilla john-1.7.9-jumbo-5, locating the
culprit was trivial.  Sorry for false alarm.  :-(

Yes, my ~2006 laptop is ia32 only.  Do I read you correctly that for both
x86/x64 builds I should prefer `i'-suffixed targets (x86-sse2i/x86-64i)?

Thanks,
