Versions

me$ ruby -v

me$ rvm -v
  rvm 1.8.0 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]

Every command is giving me same issue:

• railroad -o models.dot -M

• railroad -a -i -o full_models.dot -M

• railroad -M | dot -Tsvg > models.svg

• railroad -C | neato -Tpng > controllers.png
