Arch Linux User Repository

Thanks! I updated the PKGBUILD with the changes from your diff.

Unfortunately I no longer have the time to maintain this package as it is not used on my systems anymore.

Here's git diff to fix building in a clean chroot, try to correct the license, and clean up a lot of unnecessary cruft in the PKGBUILD:
