ldc2 has the --static option, though, looking from ldc2 --help 
I'm not 100% sure exactly what that does.

If that doesn't work we cat get a little creative:

     $ cat hello.d
     import std.stdio;

     void main()
     {
         writeln("hello, world!");
     }
     $ ldc2 -c hello.d # creates hello.o
     $ gcc hello.o /usr/lib/x86_64-linux-gnu/libphobos2-ldc.a 
/usr/lib/x86_64-linux-gnu/libdruntime-ldc.a -lm -lz -o hello
     $ ./hello
     hello, world!
     $
