It is good to see something like this, but question is why? GNU/Linux already has several package systems, plus several GUI package managers. :)
Someone just has to persuade Walter to allow Linux community to pack DMD into proper packages (RPM, DEB, autopackage, ...) and that is enough for most of us.

PS. I use my own, very simple and effective, install script which can be downloaded from http://dejan.lekic.googlepages.com/install-dmd . As a matter of fact I know there are several similar scripts...

Kind regards
