gdc for DragonFly?

[Johannes Hofmann <Johannes.Hofmann@xxxxxx>]

I would like to check out the D programming language
(http://digitalmars.com/d/). 
To get this to work on DragonFly I need to compile gcc with a D 
frontend from http://dgcc.sourceforge.net/.
Any ideas how to do this? The standard gcc tarballs and the pkgsrc 
packages for gcc don't seem to compile out of the box.
