Really?? I have found, on the contrary, that DMD is extremely easy to
build. As opposed to, say, GDC (no offense ;)), which I haven't been
able to build since gcc-4.8, likely due to the build scripts relying on
hardcoded system paths that every Linux distro changes around just for
fun.

It's as simple as:

	git clone ${url to dmd repo}
	git clone ${url to druntime repo}
	git clone ${url to phobos repo}
	cd dmd
	make -f posix.mak
	cd ../druntime
	make -f posix.mak
	cd ../phobos
	make -f posix.mak

Then just add dmd/src/ to $PATH, and off you go. I've been using this
for years, and haven't had a problem. This can, of course, be put into a
shell script that does everything, which is what I do these days.

You can add -j${NUM_CPU} to the make invocations, if you're impatient
like me and want to take advantage of today's multicore craze. I
personally use -j6.
