So partially I figured out for myself why a UML modelling tool for
Ruby
is not present yet.

The reason is not (as some here mentioned) that ruby code is so small
and ruby is so agile (although both is true) that nowone needs a
modelling tool.

The reason is more rubys dynamic nature.
* Types are not that detectable
* Variables can be changed and (re?)declared everywhere
* And ruby contains such cool / weird (?) things as instance-class
variables:
Have you ever seen this:
  class << self; attr_accessor :sides end

No? Then have a look at this site
http://railstips.org/2006/11/18/class-and-instance-variables-in-ruby

So now I guess you have better understanding why your boss should pay
you
double income if you have to build a ruby UML modelling tool.
