lizufyr  filed a orphan request for fromscratch-bin :
Not updated for a long time, and current PKGBUILD doesn't work anymore.
I have created an updated PKGBUILD and would like to maintain this package in the future.
otherwise, here is an updated PKGBUILD that builds from the deb file available from github: https://lizufyr.eu/fromscratch-bin-PKGBUILD
