Sorry for belated reply: I am not subscribed to the list, and for some

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

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)?
