Hi:

Running `make check-system` on master results in

ice-9/eval.scm:142:16: In procedure compile-top-call:
error: channel-source->package: unbound variable
hint: Did you forget `(use-modules (gnu ci))'?

make: *** [Makefile:6888: check-system] Error 1

After a quick bisect, the offending commit seems to be https://git.savannah.gnu.org/cgit/guix.git/commit/?id=fda0959a1426198f5588be691d1414807cb547cd
