[Yhc] What does Yhc need (error, ffi.h not found)

[Isaac]

Yes, I can compile that program "test.c" with gcc -c test.c
Just to test, without darcs-pulling anything, I re-ran scons on yhc, and
it worked to a greater extent than before (then erroring with:
/usr/lib/gcc/powerpc-unknown-linux-gnu/3.4.4/../../../../powerpc-unknown-linux-gnu/bin/ld:
cannot find -lffi
)
There must have been something temporary affecting that (my computer was
rebooted in between).

After darcs pull, scons errored:

scons: warning: Ignoring missing SConscript

darcs unpull'ing only those new patches that didn't look like they had
to do with ffi, scons then reached the same "cannot find -lffi" error.
