Running DMD tests

[Peter Alexander]

I'm trying to run the test suite for DMD, but I'm running into issues.

I've cloned dmd from github, and successfully built dmd, but when I run 
'make' from the dmd/test dir, I get:

   $ make
   Creating output directory: test_results
   Building d_do_test tool
   object.d: Error: module object is in file 'object.d' which cannot
   be read
   Specify path to file 'object.d' with -I switch
   make: *** [test_results/d_do_test] Error 1

Do I need to set up my environment differently to run dmd in 
development? How can I get around this?

Note: I'm running OSX 10.6.7

Thanks
