1.9.3 might be good, too, but I don't know how much version
proliferation we can deal with.  Four versions of Ruby and four versions
of most gems would be a bit out of hand, IMO.

Your patch looks good.  You should send it on over to guix-devel at gnu.org
for good measure and I'll apply it.

Now, we need something like 'package-with-python2'.  I think it should
be a procedure that accepts a ruby package and a gem package.  It will
replace the version of ruby used to build each gem in the dependency
tree.  For efficiency, the procedure will be memoized to avoid a lot of
duplicated work.

If I may change the subject slightly, I'm curious about your work on
Nokogiri.  I haven't yet figured out how to build a gem that has the
native extensions packed within.  We must avoid the normal rubygem
method of building the native extensions upon installation.  Do you know
how to do this?

Thanks!
