Could you try setting:

  export NIX_CURL_FLAGS="http_proxy=\"http://some-proxy.com:3128\""

Before the build, I remember that working at one point when setting
http_proxy didn't work. I obviously don't use that anymore since my
script work for me.

I'm not on 14.04 but will try to build behind a proxy on 14.04 once I
get some time.
