Unfortunately, as you found, often the dependencies needed for testing 
are sometimes not listed at rubygems.org, since it is not common for 
tests to be run as part of the "gem install" installation process.

That seems to be the case, unfortunately. There also seems to be some 
other gems in the Gemfile which aren't yet packaged for Guix. There are 
also a number of packages in the wip-rails branch on savannah which 
might be of use - these aren't quite ready yet but if there was interest 
I could finish them off.

If the number of packages needed gets too large, then there may be a 
case for not running the tests in some packages.

Good luck.
