Paul et al,
I will try to do this tonight or tomorrow, though it will not be built
with th system tools because I have yet to get that tto work locally
(spent a good chunk of this morning trying).
I will send a separate messaage regarding those difficulties as well so
that we can at least confirm that they are due to a malconfiguration on
my part.
Best,

Brian has been helping with the build, but I am still looking for

help with.
