Change:
buildr147 in is a rubygem for the Apache Buildr build system. The upstream 1.4.7 release of Buildr has a few serious regressions compared with version 1.4.6 that prevent some projects from compiling with Buildr 1.4.7. Would it be possible to keep the (old) expression for 146 around, alongside 147? There should be a way for nix expressions to specify a composition with 14_6 specifically (for projects that are hit by the regression).
I've worked around this problem now, so if I'm the only one complaining, feel free to close the issue.

<ins> ** Status The code in master as of June 2015 should be able to prepare a bootable NixOS for Raspberry PI 2. There are still some drawbacks: NixOS does not provide a /boot/config.txt (the FAT32 partition). Making NixOS work in the Raspberry PI 2 is mainly the result of the recent work of ambro718, Dezgeg and viric (#nixos@irc.freenode.net). ** Download If you want to test, you can flash this 4GB SD image (DOS partition table + fat32 + ext4 rootfs): magnet:?xt=urn:btih:0def3f6acb3bceddb22cb24098f58e40e2853ec2&dn=rpi2-nixos-4b09501f2-img.xz&tr=udp%3A%2F%2Fopen.demonii.com%3A1337&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80 Then you should be able to nixos-rebuild any configuration.nix changes. The image is the result of a "nixos-install" alone. No root password has been set, and it does not include a nixpkgs checkout or channel. In fact I (viric) created the FS into a NBD, not a real SD, to create this image. </ins>
