QTR-Quadtone RIP

I suspect this has been discussed before but I could not find anything through search. Is there a version of QTR that runs under Linux? I currently use Gutenprint 5.x, and the MIS Eboni inks. The results are good but I'd like to give QTR a try to see what it offers.

BTW, If there are others that use the above combination I'd love to discuss details.

Thanks
