Nitrogen failing to `make`, rebar failed

[gumm]

This appears to be an issue related to erlang being installed via asdf:

Build It with Nitrogen (Leanpub)

Currently I made it work by adding erlang installation folder to the path, so that the Erlang executable from the installs/erlang/24.2.1/bin is used instead of the one from shims folder, and when the script is looking for the erts-12.2.1 folder under the parent directory of bin, it is finding it.
