All you have for druntime are .di files (so basically header files rather than 
full-on source files) and the library file with the compiled source, so you don't 
have the source. Now, as to _why_ that's all you have, I don't know (the .d files 
come with phobos). But you need the .d files for the full source, and without 
them, you won't be able to use CTFE with the functions in them.
