Yes, it's probably related to the release.  Some runtime hooks 
were taken out of object.d and moved to `rt/array` to help set 
direction for a GSoC project that is in the process converting 
many runtime hooks to templates, and to help prevent object.d 
from becoming even more unwieldy than it already is.  Move such 
refactorings are planned.

I don't know what digger is doing, but from the error messages, 
it appears that the new files in `rt/array` can't be found.  I 
believe the build is trying to use a new compiler with an older 
or existing runtime.  You'll need both the latest compiler and 
the latest runtime together for them to work.

If you can identify a bug in the makefiles, or some other such 
problem preventing the build, let me know and I'll try to fix it 
right away.
