[Nix-dev] Problems getting started with nix

[Maarten Derickx]

The command wich I started running during my previous mail just failed
btw. The command was:

nix-env -i hello

I pasted the last few lines of the output of this command to:

http://pastebin.com/Hppwb6Pk

It should have enough info to read of the exact errors.

Thanks in Advance,
Maarten Derickx
