Inspect or clean up the working tree error when installing Ruby 2.1.3 on Mac OS X 10.9.5

Did you try this:

CC=/usr/bin/gcc rbenv install 2.1.3

ruby-on-rails ruby unix homebrew rbenv

I had to remove the existing openssl that came with macOS and instead install from brew with brew install openssl.

NOTE: I also had to disable SIP with csrutil disable and then remount root with writable permissions, with sudo mount -uw /.
