3.5+ has not, and never will arrive on wheezy. We've a stretch based lcnc
installer now, but I've got stretch on 2 machines now, and I'm not
impressed. Making networking actually work makes work a 4 letter word.

Not sure where the problem is Chris, but A: its not my code, and B: a
potentially very useful machine vision utility to a cnc machinist
actually works like the teats on a boar hog. Useless if it cannot be
actually used on a daily basis. I've tried to make it work with pyvcp,
and with gladevcp. Essentially the same errors (none reported) and
behavior on both gui interfaces. With 3 different cameras. That, in 3
versions of it, is the main reason I've been mostly lurking on this list
for several years.
