Actually i did find a way out !!

Earlier in the loop, I was doing:
             desc = opt.description

Now I do: opt.call.description

      cmdtext = "Commands are:"
      @commands.each_pair do |c, opt|
        desc = opt.call.description
        cmdtext << "\n   #{c} : #{desc}"
      end

Works.

I modified my app to use this, it was easy since both use OptionParser.
I added aliases. But my app has slightly more complex aliases where one 
command maps to multiple words. Working on that currently.
