Hello Dave,

Come back to expect pb:
	o I just grab dpkg src and while I rebuild it localy I noticed that:
./configure [snip] --enable-threads
[snip]
checking for building with threads... configure: WARNING: Expect is not fully thread-enabled.  Although significant work has been 
done towards that goal, it is not complete.  Continue compiling at your own risk.
no (default)
[snip]
	? do you also used this '--enable-threads' options

	o I also grab the latest 5.43.0 release and btw lfs recommended the patch: expect-5.43.0-spawn-1.patch
	  <http://lfs-matrix.net/lfs/view/development/chapter05/expect.html>
	? do you already test it?

Thanks,
	Joel
