It may be that your LIBRARY_PATH variable is not set up correctly while in tmuxinator. It seems that you have installed it into a non-default directory, so the shared libraries needs to be on the library path as well.

I would recommend using a Ruby version manager RVM. It sets all of the environment variables to use the right ruby for you. You just need to run the shell with the login flag for it to work.
