MySQL Question

Error Installing Mysql2 on OSX

Attempting to install a specific version Mysql2 Gem. And I get this:

sudo gem install mysql2 -v '0.3.20'
Building native extensions. This could take a while...
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.

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/5.7.16/lib
creating Makefile

make "DESTDIR=" clean

make "DESTDIR="
compiling client.c
compiling infile.c
compiling mysql2_ext.c
compiling result.c
linking shared-object mysql2/mysql2.bundle
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [mysql2.bundle] Error 1

make failed, exit code 2

For reference I ran
brew install mysql
beforehand and it ran successfully. Also I tried uninstalling all versions of
's mysql references just in case.

Is there something im missing? I've looked around and most pages point back to making sure you run
brew install mysql
which I have.

In case I wasn't more clear with my above explanation, the failure I am getting is after successfully running
brew install mysql
the error is from trying to install the gem afterwards via
gem install mysql2 -v '0.3.20'

Any idea?

Just for reference what ended up working was xcode-select --install which seemed to install the OpenSSL libraries which took care of the ld: library not found for -lssl issue.
