I disagree. The easiest way to see rubygems is to see it as "tar on
steroids". If you consider it differently, then you open the door to
hacks to try to integrate gems with apt. Since nobody seem to want that
on the rubygems side, this is likely to fail or stay in an half-broken
state, and make everybody unhappy. (rubygems users, and Ubuntu
maintainers that will have to deal with the bad press)
For the same reason, I don't think that we should package gems, because
that would be about the same as packaging tarballls. The only sane way
to do that would be to have empty packages that do "gem install foo" in
It's a shame that a big part of the Ruby community doesn't acknowledge
that other packaging systems exist. But working around that social
problem using technical hacks is not going to lead anywhere.
