druntime contains the D runtime. It's required for any D program to work. 
Phobos is D's standard library and thus uses druntime. It's not actually 
required, but you're not likely to write a D program without it. Both are 
provided with dmd combined as a single library (libphobos.a or phobos.lib, 
depending on the OS). The core.* modules are in druntime, and the std.* 
modules are in Phobos.
