That=92s my guess too, based on the configure output from libffi.

"LD=3D/usr/bin/ld"  "NM=3D/usr/bin/nm -B"  "RANLIB=3Dranlib=94

The easiest path forward would be to set TOOLS_PREFIX in Makefile.inc1 =
to an appropriate prefix (see XMAKE in Makefile.inc1, etc). I suspect if =
you add this variable to NXBENV and tweak it appropriately, things will =
just work.
