Guix, I've noticed some time ago that the biber version that we currently have is incompatible with the texlive revision we have packaged.
Incidentally, since the latest core-updates merge, biber does not pass its test suite anymore due to the hardcoded `perl-unicode-collate'-related hashes. I think we need a more sustainable (and dynamic) fix for this, as this is not the first time this has happened. As far as I know, biber has no dependents other than itself. I could also downgrade it 2.11 so it works with our texlive packages again. Should I simply revert the "gnu: biber: Update to 2.12." commit, or only adjust the [source] and [version] fields of the biber package? I can push a short-term fix that involves disabling the test suite for biber nonetheless, as this seems to be required for both version 2.12 and 2.11. Thoughts?
