This patch should be committed before the one I sent previously (emacs-queue)

This is an excerpt from the build log

In toplevel form:
test/pkg-info-test.el:34:1:Error: Cannot open load file: not a directory, pkg-info-dummy-package
Compiling /gnu/store/38j122ni4zm2vcmfcyxhpd6l3qn8gh6g-emacs-pkg-info-0.6/share/emacs/site-lisp/guix.d/pkg-info-0.6/test/test-helper.el...

After pkg-info-dummy-package can't be found it gets successfully compiled

I think this is not a problem and the resulting build can be delivered to Guix users.

I report this here for completeness
