A few additional thoughts to add to my previous reply:

I misunderstood this the first time, and now I understand what you
The ruby-build-system doesn't specifically disallow downloading other
dependencies because it's not possible to do so from the build container
where only the loopback network device is available.

I've decided that we should try to report such bugs upstream and
temporarily disable the test phase until the problem is resolved.

So, right now I'm leaning towards just using the .gem archives from
rubygems.org. I'm going to merge your rubygem-build-system with the
ruby-build-system and see if I can convert all of the existing Ruby
packages to it without serious loss of test suite coverage. I'll ping
you when I have results.
In the event that we want to use a tarball instead of a gem archive, we
can easily handle that with a build system argument like #:build-gem?
that defaults to false, and an 'unpack' phase that DTRT with .gems *and*
If this works, the next step would be to write 'guix import rubygems' to
How does that sound? Thanks for bearing with me.
