Hi Guix, On the current core-updates branch, font-gnu-freefont fails to build with the attatched build log. Based on the messages about syntax errors, it looks like gnu-freefont is not compatible with python3, and instead needs python2. However, we already try to do this in the package definition: ;; replace python 3 with python 2 ;; python 3 support commits aren't yet released in 20120503 ;; so freefont needs python 2 support in fontforge (native-inputs `(("fontforge" ,(package (inherit fontforge) (inputs `(("python-2" ,python-2) ,@(package-inputs fontforge))))))) Best, Jack
