Hey,

Thanks for these patches Pierre, I haven't looked at them in detail, but
one I did spot was ruby-tilt. I've already sent a patch for that here
[1]. In fact, maybe have a look through the patches in that bug, as that
will at least give you an idea of how I've been packaging some Ruby gems
recently.

I haven't checked the patch, but often the test suites are omitted from
the archives published to rubygems.org. This avoids users who use the
rubygems package manager from downloading the tests unnecessarily (as I
don't believe rubygems provides a way to run the tests), but obviously
doesn't suit packaging for Guix.

Fetching from the version control repository is a good way of getting
all the tests, but obviously that isn't what the gem importer generates.

I think theres a commit on the staging branch to pass the --verbose flag
to gem install, which may be revealing.

In my opinion, if you think someone might use it as a Ruby library,
stick with the ruby- prefix for consistency. Otherwise, call it what you
think makes most sense.

If you're confident that the more recent versions of the dependencies
work, then I'd recommend patching the source to loosen the dependency
constraints.
