dynamic PATH for ruby gems
dynamic PATH for ruby gems

This sets the path for ruby gems dynamically instead of looking for a
specific ruby version. There may be a small performance hit from running
ruby every time I open a shell, but measuring it with 'time' shows
something like 0.03 seconds. Not completely terrible. We'll see.
