Did you pass a block? Actually I missed cmd.run in there (what do you 
expect at quarter to two?).

You can do it like this:

ExecCmd.new("rake"){|cmd|
	puts cmd.success?
	puts cmd.output
}
or like this:

cmd=ExecCmd.new("rake")
cmd.run
puts cmd.success?
puts cmd.output

But a nice sideeffect of this implementation was
cmd1=ExecCmd.new("blabla")
cmd2=ExecCmd.new("blabla2")
cmd3=ExecCmd.new("blabla3")
[cmd1,cmd2,cmd3].each{|cmd|
	cmd.run
	#do stuff with it
}
And afterwards you also have a crude benchmark for each command i.e. :)
[cmd1,cmd2,cmd3]each{|cmd|
	if cmd.run?
		status="succeeded"
		status="failed" unless cmd.success?
		puts "#{cmd.cmd} #{status} in #{cmd.exec_time}s"
		puts "Log:\n#{cmd.output}" unless cmd.success?
	else
		puts "#{cmd.cmd} was not executed"
	end
}
