Digger problems

[via Digitalmars-d]

When a system-wide DMD is installed, Digger seems to use that to 
build Phobos and druntime instead of the freshly built one. This 
results in funny errors like:

src/core/time.d(99): Error: undefined identifier '_xopCmp'
Error: Internal Compiler Error: _xopCmp not found in object 
module. You must update druntime

(Tested on Linux x86_64, latest Digger from Git, trying to bisect 
between master and 2.061.)

I guess I must be doing something wrong, because it seems normal 
to have DMD already installed when using Digger. Has anyone else 
experienced this?
