I think that imagemagick is only required while building, so it can be a

You can check what packages the built output refers to: $ guix gc
--references $(./pre-inst-env guix build awesome)

Imagemagick is not in the list.

Thanks for this! I had assumed that the "guix lint" would tell me about something like that, given the check "inputs-should-be-native".

Is it possible for those references to be "wrong"? For there to be something which is required at runtime, but doesn't show up in a "guix gc --references" check?

I noticed that several of the files have the "or later" text. If they
are all like that, we could use gpl2+. Did you check if there are any
files with licenses besides GPL2+?

The lua files (in lib/) don't have a license heading beyond a copyright year/author in the luadoc tags. Everything which has a license heading seems to be gpl2+ (I had missed the "or later" text, but I've updated it now).
