I don't think so, I get a different exception which looks to me like an
incompatibility between the tests and rspec@3 in Guix. This
`last_comment' related error is a issue between Rspec 2 and more recent
versions of Rake, and I've updated the comment as below to try and
explain this.

+    (Build-system ruby-build-system)
+    (arguments
+     '(#:phases
+       (modify-phases %standard-phases
+         ;; Avoid a incompatibility between rspec@2 and rake. Using rspec@3
+         ;; would be nice, but the tests look to be incompatible:
+         ;;
+         ;; NoMethodError: undefined method `last_comment'
+         (replace 'check
+           (lambda* (#:key tests? #:allow-other-keys)
+             (when tests?
+               (invoke "rspec"))
+             #t)))))
