If I create an example analogous to yours, it seems OK.  However, I was dealing 
with a case where the package is at the 2nd level of the subdirectory hierarchy:

     std/random2/package.d
     std/random2/generator.d
     std/random2/distribution.d

and so on.  That might have something to do with it.

Well, quite.  dmd doesn't resolve dependencies, it expects you to pass it all 
the necessary source or object files ...

... like this.

I think that there must be a problem with packages that are in the 2nd rather 
than 1st level of the subdirectory hierarchy.
