I am sure there is some way to get it to print out exactly what 
it is doing. I've done it before when trying to figure out some 
compilation issues ... unfortunately it was a while ago and the 
machine I am at now doesn't have dub (or D for that matter) 
installed.

Maybe you need to give the the dub -v (--verbose) option.  Type 
'dub help' to check - again I can't do that right here.
