ruby-build: Ruby 2.2.0 build fails on MacOS 10.10.2

I’m consistently getting a failure trying to install Ruby 2.2.0 on Yosemite 10.10.2. I tried the recipe in post:

https://bearmetal.eu/theden/install-ruby-2-dot-2-0-yosemite-openssl-error/

but can’t get it work on my machine. I’ve installed openssl using brew and modified the PATH variable so that this version of openssl is found first.

$ openssl version -a

I tried using rbenv to install because installing via rvm failed (with I’m pretty sure the same error).
