[ Forgot to the CC the list. Apologies for the duplicate email, Ricardo ] Hi Ricardo,
Rake 10.4.2 comes with Ruby 2.2.3: $ guix environment --ad-hoc ruby -E "rake --version" rake, version 10.4.2 Is this for use with an older Ruby version? If so, we should make that explicit by altering the build system arguments. This reminds me that I need to submit a patch for my 'package-with-ruby' procedure that behaves a lot like 'package-with-python2' but works with any Ruby package object. - Dave
