Installing 'nodejs' installs '7f' library instead

[wemrysi]

I'm not sure if this is an issue with the nodejs package, the nodejs-7f package or with nix itself, but in the current version of the unstable channel, nix-env -i nodejs installs the nodejs-7f library and not node itself.

I suspect this has something to do with the 7f library beginning with a number and that number being greater than the existing versions of the nodejs package, the highest of which is currently 0.12.0, however my knowledge of nix internals is nonexistent, so this is pure speculation.

The following terminal transcript illustrates the issue

Yes that name must not have -7f.

[flosse]

yes, I think we can safely remove the 7f package, it's not used by any other package.

[wemrysi]

Would it make sense to rename it instead? Maybe to lib7f or sevenf? Are there any precedents or guidelines for how to name packages that begin with a number?
