I haven't used Arch in a while now, since I finally converted to
Ubuntu last year. I'm not sure if there is anybody else using ROS
actively on Arch, but if so they will hopefully chime in.

To get that error, did you download the rosinstall script and just run
it, or did you try to build rospack manually?
