The 4:3.3.2-1 is a debian version number based on 3.3.2, yes. I was
fiddling a little more and it looks like the qtruby package builds and
installs its own smoke, so I tried uninstalling Debian's libsmoke* and
rebuilding qtruby. 1.0.10 wouldn't build because of a libtool problem,
but 1.0.9 did. I installed it and had the same problem: a blank window
with no widgets.
