I wanted to use guile3 port long ago, but auto-tools just fails to build on arch. On ubuntu it’s okay but I don’t know why. Now cmake does the work! After the first startup, it runs way smoother than guile1.8 port :->
Currently the PKGBUILD pulls from my fork, you can change it to guile3_branch_2.1 branch of main repo if you want.
