debug flag being ignored

I'm trying to run 'ruby -d foo.rb' and the d is either ignored or I don't
understand how it works. The code just runs as if there is no -d option.

Does this require something at compile time of Ruby that I might have overlooked?

Maybe you wanted ruby -rdebug -d foo.rb ?

"-d" sets $DEBUG to true.

Does your code execute something when $DEBUG is true?

For example:

puts "Important intermediate value: #{my_critical_var}" if $DEBUG
