Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load
Setting libpath to /usr/local/Cellar/mysql/5.6.25/lib
creating Makefile

I tried uninstalling every version of
I installed via homebrew and reinstalling them, like so:

brew uninstall --force mysql && brew install mysql

Then running:

sudo gem install mysql2

As suggested by a number of similar questions asked on here, but it still results in the same error as above.

Please could someone offer guidance on how to get this up and running?

Answer Source

The error log says:

ld: library not found for -lssl

So, you need to install libssl:

brew install openssl

Hope it helps.
