I think our messages crossed each other; I wrote:

  The other option would have been to add ‘python’ to ‘propagated-inputs’,
  which would also have taken care of sub-directories other than lib/.

  As a side-effect, it would also pull in the ‘python3’, ‘pydoc3’,
  etc. commands, but I think it cannot hurt.

So yes, I think we should try this.

What about making this change in a branch, letting Hydra build it, and
then merge it if nothing broke?

We’ll also need the patch from
<http://lists.gnu.org/archive/html/guix-devel/2014-10/msg00364.html> in
this branch.

Do you want to take care of it?  :-)

TIA,
