Installing Erlang has been somewhat of a pain. When trying to make sure I have the version I want, relying on the ppa has not been that great. Thankfully someone has shared with me an amazing tool, kerl.

Somewhat like rvm for Ruby, kerl keeps a list of the Erlang versions you can build and has ways to switch between versions. While not as “feature complete” as rvm, this tool definitely fits the bill for me. Trying to keep up with Erlang and learn the language is now a bit easier with this roadblock out of the way.
