Yeah. I ran into the same problem with my own build tool. There wasn't
previously an rt folder in the imports. It was all hidden in the
implementation, and my build tool didn't copy it over, resulting in
confusing errors at first when druntime was recently changed to have an rt
folder in the imports. I think that for druntime, it currently works to just
copy over everything in the import folder, whereas with Phobos, you have to
copy over specific directories (std and etc IIRC). So, for Phobos, you can't
just grab everything from a single folder, and it may have been the case
with druntime at one point that you couldn't either (I'm not sure). So, it
doesn't really surprise me that digger broke. Any time that a tool is having
to duplicate any logic from the build system (even if it's just which files
to grab to install rather than for the build itself), it risks breaking any
time that the build system is altered.
