What is the correct way to run the auto-tester tests on FreeBSD?

[Jeremy DeHaan via Digitalmars-d-learn]

I'm trying to figure out how to run the auto-tester tests locally 
on FreeBSD and I'm running into an issue. I managed to get the 
tests to run on a 32 bit after a fashion, but I can't seem to get 
the tests to run successfully on the 64 bit version.

Here's what I've done so far.

git cloned dmd, druntime, and phobos.

ran 'gmake -f posix.mak auto-tester-build' in the dmd directory

ran 'gmake -f posix.mak' in both druntime and phobos directories

ran 'gmake -f posix.mak auto-tester-test' in the dmd directory

The tests start, however after the first test (issue8671.d) I get 
a strange error message:
Error: module  is in file '.d' which cannot be read

Do I need to set up the system in a specific way to get these 
tests to properly run or is something else going on here? Note: 
this is using the master version of each repo, I'm not trying out 
my own branches yet.
