Simple I know, but could use some help compiling with make

I had exactly this problem too, I asked on the Derelict forums:

At the moment I've resolved this by building Derelict with make, first a normal full
build, then a second run using the cleandi target, which removes the generated di files.
I've set up the Derelict lib and include paths in dmd's sc.ini file, so I just have to
call 'rdmd main.d' to build and run.
