@hisacro: The faust dependency is purely optional (see my previous comment) and has been there for at least 5-6 years.
If you get a build failure, then the issue is elsewhere - probably either in the pkgbuild or upstream given the work in progress to modernize the build scripts.

This package will automatically retrieve and build the latest development snapshot of Guitarix from git.
It does not need to be updated on every release, so please do not flag out of date unless the build itself breaks or in case of an actual packaging issue.
If you are looking for the latest official release instead, see https://www.archlinux.org/packages/community/x86_64/guitarix2/
