SCons is a build tool that does exactly what make does, except that it does it way better.  This is a tool plugin that makes it simple to compile D source with SCons:

ex:

# builds theProgram.exe on Windows, theProgram on linux

import dmd

env = Environment()
dmd.generate(env)

env.Program('theProgram', src = Split('''
   a.d
   b.d
   TheClass.d
   TheOtherClass.d
'''))
