To run a program from the current directory you have to use ./ruby
otherwise it looks in the path first, I think. So the best thing is
to that folder to the path. However I strongly recommend using rvm
(or rbenv), rather than installing from source yourself. It is much
easier and you can install ruby and rails in a single command, plus
have access to different versions on the same machine very easily.
