I don't know exactly what the deal with unit tests and libraries is, but it 
wouldn't surprise me at all if you have to compile a module into a binary to 
run its unit tests. Phobos (on Linux at least) is set up to build each module 
separately to run its unit tests. I can see why you'd want to do this, so it 
may be worth creating a bug report or enhancement request for it, but I have 
no idea whether it's supposed to work or not.
