Hi,
the link with installation scripts (PKGBUILD) [1] for Arch Linux [1] is dead and I guess has been dead for about a month now, since the Arch User Repositories (AUR) has been moved to a git-based backend [3] and the kwant-related packages have not been moved. I took the PKGBUILD files for tinyarray and kwant from a mirror [4] and updated them. They build on my system, but any comments before I reupload them to the AUR are greatly appreciated. You can find the new PKGBUILD files attached.
best regards, Jörg Behrmann
