I got this nasty error (slimerjs Can not resolve required module encoding):
Error: Cannot find module 'encoding'
    at Function.Module._resolveFilename (module.js:336:15)
    at Function.Module._load (module.js:286:25)
    at Module.require (module.js:365:17)
...
... so I thought, maybe I could add a couple of console.log in this module.js, and thereby trace what files/paths are considered for loading.
However, I cannot seem to find this module.js anywhere:
$ find ~/.nvm/ -name 'module.js'  # nothing
$ find /path/to/slimerjs-0.10.1-pre -name module.js  # nothing
Then I go to https://github.com/nodejs/node/search?utf8=%E2%9C%93&q=module.js - and I get a whole lot of hits, just not the file module.js :/
Where can I find this file? Also, is it somehow compiled inside node, as I cannot seem to find it standalone?
