Guix complains that it cannot find gpg when I call "guix import gnu
<package>". 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.
