Hi Christian,

Thanks for the timely response and resolution. I did indeed miss that
configure script warning about uuid, so thanks for putting a hard exit when
missing the dependency for it.

Got another make error, this time for gigedit:

Got some deprecated warnings too, but not sure how relevant they are.
