I am trying to define the gnurobots package using guix import. I try the following and get the corresponding results:

This is fixed when I install gnupg. It appears guix needs gnupg as a propagated input for this function to work statelessly. If anyone has a contrary opinion, please express it. I will make, test, and submit a patch on Monday if nobody beats me to it. --Jesse
