Hello, I tried to nixos-rebuild with the trunk nixpkgs today, and I found at least two URLs that don't work, and thus the build fails: http://ilbcfreeware.org/documentation/extract-cfile.awk http://www.riverbankcomputing.co.uk/static/Downloads/PyQt4/PyQt-x11-gpl-4.8.5.tar.gz Can someone provide some fix for those? Thank you!
