An update:  

I'm back to using dsss successfully with acceptable build times.   I followed 
a setup similar to Frank's and managed to install dsss 0.75 correctly such 
that it builds a dwt-based project in approximately 38 seconds (with -gc 
flag active).  For debug/test builds, I avoid building the dwt library itself 
and simply reference the dwt directory as a source library while compiling 
the test project.  With a slight adjustment to the etc/rebuild/dmd-tango-posix 
config file, I'm now content with the ease of building sample projects via 
dsss.

Incidentally, I was originally doing all this on a linux distribution installed 
in a virtual machine (VirtualBox originally, then Vmware) which probably 
slowed the build times further.  I have since moved to using colinux under 
Windows XP which has proved to be a delight to work under.  For those interested, 
there are a couple of linux distribution projects that use colinux as there 
base.  It basically allows you to run linux and linux programs full speed 
as a win32 service.  X windows programs can run seemlessly with win32 apps 
by using XMing which is installed as part of the package.  The apps run very 
fast since they are not being run inside a virtual machine!

Here's the link to just one of the colinux distribtuions (based on Ubuntu, 
the one I am currently using):

And here's a link that list a few other options:

You should still have a fair bit of RAM to run coLinux.  I've got 1 GB on 
my laptop, but 2+ GB probably would be better.
