Hi Guix,

attached are a couple of patches that resulted from a recent attempt to
traverse the dependency graph for a dependency of some tool I wanted to
package.

I’m not happy with ‘0007-gnu-Add-ruby-rb-fsevent.patch’ because it is to
be used on a Mac OSX, but unfortunately this is a required input for
a more general file system library that is in my pipeline.

I’m also not happy with disabling tests for ‘ruby-yard’, but I didn’t
find a way to make them pass.
