Excellent Thank you.
I think my problem was scope then.
Here's what I be doing and it now works like a charm.

$ cat cmd1/cmd_bar.rb 
module Command
  def cmd_bar
    puts "cmd_bar one called"
  end
end

$ cat cmd2/cmd_bar.rb 
module Command
  def cmd_bar
    puts "cmd_bar two called"
  end
end

$ cat testcmds.rb     

class Foo
end

def load1
  cmds = Dir.glob("cmd1/cmd_*.rb")
  cmds.each {|c| load(c)}
  Foo.send(:include,Command)
end

def load2
  cmds = Dir.glob("cmd2/cmd_*.rb")
  cmds.each {|c| load(c)}
  Foo.send(:include,Command)
end

f = Foo.new

load1
f.cmd_bar

load2
f.cmd_bar

$ ruby testcmds.rb 
cmd_bar one called
cmd_bar two called
