dub dustmite struggles

[DanielG via Digitalmars-d-learn]

I can't seem to figure out what dub's dustmite command is looking 
for with its regexes. No matter what I try - no matter how simple 
- the initial test fails.

I am able to run dustmite standalone just fine with the following 
test script:

cd example
dub 2>&1 | grep -F "ScrollView6__initZ+0xd8): undefined reference 
to \`internal'"

However, when I attempt using 'dub dustmite' with --linker-regex 
(or --linker-status, even), the initial test always fails. I've 
also tried simplifying the regex on the assumption that I'm not 
escaping things properly - to no avail.

Is it perhaps something to do with my project structure? My 
project is a library containing an /example subfolder, containing 
an application dub project, and that's where my linker error 
occurs, not in the library itself. So that's where I'm attempting 
to run dub dustmite as well.
