Dear guix hackers, unison (gnu/packages/ocaml.scm) does not build (the install-doc phase fails) on core-updates-frozen, because it lacks at least texlive-fonts- ec as an input, and then it fails with:
dvips: ! Couldn't find header file: l3backend-dvips.pro I tried to add texlive-latex-l3backend, but it does not fix the problem. Best regards, Vivien
