and the package ’ghc-language-c’ had been updated to 0.8.1 by the commit19b29882878a6558e5f16d587265eb3a0c0cdec6 (Jan. 2017). So the package isprobably broken since 3 years. Four fixes are possible: 1. add the package ’firstname.lastname@example.org’ introduced by 2d2388e243d31f00b31b36b8ada76876b6fdacf2. 2. turn the package as “private” or at least deprecated. 3. move it to guix-past. 4. remove it. (Note that upstream is stalling; last commit 4 years ago.)
I am in favor of option #4. Or maybe someone wants to fix?
