But unless I'm using a function of guix that depends on gpg, guix is not broken, so gpg is not an input or propagated input of guix. I think we have the same situation here. Evolution is functional without GPG, and handles itself fairly well when gpg is not found. Try installing gpg locally and see if it stops complaining. If so, we have a solution. If not, we should consider adding GPG as a propagated input to Evolution.

That does fix the problem itself, but I personally believe there should be a better way of handling "optional" inputs -- "optional" because in at least some if not many cases, people would expect them to exist. Guix' emacs has imagemagick as input for instance (even though it is optional) and a separate emacs-minimal exists as the version without it and other optional inputs. I think this pattern could be applied more broadly.

I see my logic was faulty. Some of the packages I contriubted list optional inputs, and the people who committed them added comments saying we should plan on packaging those optional inputs and adding them as inputs. Perhaps your first suggestion, being to add gpg as an input or propagated input to evolution, is indeed the best solution. This brings us back to the original question, which approach is better? I am not familiar enough with guix security features to make a proper conclusion, but I can try anyway. I think adding gpg as a propagated input to evolution is better because it garuntees evolution will use the most recent version of gpg when gpg is updated. However, if a user uses gpg not exclusively for evolution, but gets it by installing evolution, then when evolution is removed the user will lose gnupg. Though that would be mostly the user's problem, propagating inputs is a side-effect. On the other hand, if gnupg is an input, when gnupg is updated and rebuilt, evolution must be rebuilt. I do not know how guix determines if grafts should be applied, so I do not know if grafting will prevent this issue. I would like to see what the guix maintainers think before I make a patch, but there's nothing stopping you from making such a simple patch and sending it to this bug thread.
