  You could also use Rvmmin
> that has bounds, or nmkb from dfoptim (though you cannot start on bounds).

One 'negative' for dfoptim is that is doesn't automatically generate the 
Hessian (as far as I can tell). Rather nice to be able to do so for 
other calculations that usual follow after the optimization. optimx has 
a control option for that.
