I'm unable to run gl_tail on OS X 10.9 with ruby 2.0.0p451 (2014-02-24 revision 45167) [universal.x86_64-darwin13]

$ ./gl_tail
Rubygems and/or bundler missing.

I had the same problem... You need the bundler gem gem install bundler (maybe with sudo depending on your system). Then go into the gltail directory and run bundle install. Then you will need to invoke gltail from where the config file resides in (which it will ask you to generate if you don't have one).
