Hi all, Attached is a patch to make the building gems with native extensions reproducible, and a another to introduce a phase to remove `git ls-files` in Rakefiles as suggested by Dave: http://lists.gnu.org/archive/html/guix-devel/2016-06/msg00262.html
With these patches and some other small fixes not mentioned most/all of the Ruby packages build reproducibly. Thanks as usual for any review. ben
