[Nix-dev] break purity

[stewart mackenzie]

Okay, I'm having a few problems implementing this, if you wouldn't
mind taking a look at this please:

This is the package level default.nix which calls
`buildFractalideComponent`: http://nixpaste.lbr.uno/ZTwRzV0-?nix
Typically found here:
https://github.com/fractalide/fractalide/blob/master/components/drop/ip/default.nix

Here is the implementation of `buildFractalideComponent.nix`:
http://nixpaste.lbr.uno/GmbsNjmk?nix
Found here: https://github.com/fractalide/fractalide/blob/master/build-support/buildFractalideComponent.nix

Here's my error message:

[stewart at rivergod:~/dev/fractalide/fractalide]$ nix-build --argstr
debug true -A components.drop_ip
error: value is a function while a set was expected, at
/home/stewart/dev/fractalide/fractalide/components/drop/ip/default.nix:15:21
(use ‘--show-trace’ to show detailed location information)

The error arises on the last line of default.nix
