In the top level of your Ruby source directory should be the compiled
ruby program.  The problem that this path is not in your PATH
environment variable, so simply invoking ruby as "ruby" will not find
it.  There are a couple of options available to you:

1) Add the path to the directory containing the ruby program you built
to your PATH environment variable:
  PATH=/path/to/ruby/source:$PATH
2) Run ruby using an explicit path to ruby such as:
  /path/to/ruby/source/ruby calc.rb

There are other variations on these options, but these are the basics.
