If your trying to compile a dwt project from the now dwt ports, you will 
have to install Tango first. As for the compiling command, there are a 
lot of libraries to reference. I use dsss for building and for a simple 
program this is the command it generates for rebuild:

/usr/local/bin/rebuild -Idsss_imports/ -I. -S./ -I/home/he/d/include/d 
-S/home/he/d/lib/  -I/usr/local/include/d -S/usr/local/lib -I/home/he/d/
include/d -S/home/he/d/lib  -oqdsss_objs/D -L-lgtk-x11-2.0 -L-lgdk-
x11-2.0 -L-latk-1.0 -L-lgdk_pixbuf-2.0 -L-lgthread-2.0 -L-lm -L-
lpangocairo-1.0 -L-lfontconfig -L-lXtst -L-lXext -L-lXrender -L-lXinerama 
-L-lXi -L-lXrandr -L-lXcursor -L-lXcomposite -L-lXdamage -L-lX11 -L-
lXfixes -L-lpango-1.0 -L-lgobject-2.0 -L-lgmodule-2.0 -L-ldl -L-lglib-2.0 
-L-lcairo -g -gc DrawingBoard.d -ofDrawingBoard 

So my suggestion would be to install dsss for building the projects. If 
you do you can switch the default in the rebuild configuration directory 
to dmd-posix-tango And the -dc= flag might let you change it on compile.
