Module cannot be reached when adding ddb package

Hello,

I am trying out vibe.d (and D and DUB) and have successfully started vibe.d using DUB.

I then attempted to add the PostgreSQL ddb package, by changing my dub.json file to:

{
	"name": "foo",
	"description": "A simple vibe.d server application.",
	"copyright": "Copyright © 2014, scmjpg",
	"authors": ["scmjpg"],
	"dependencies": {
		"vibe-d": "~master",
		"ddb": "~master"
	},
	"versions": ["VibeDefaultMain", "Have_vibe_d"]
}

and added import postgres.db; to my app.d file. Note, this module is in a file named postgres.d that starts with the line module postgres.db;.

However, running DUB results in the error module db is in file 'postgres/db.d' which cannot be read:

I managed to get the server to build, by running the command with the two ddb source files included:

dmd -c -of.dub/build/application-debug-linux.posix-x86_64-dmd-CCED7B49303458DB3CB3B179A9415335/foo.o -debug -g -w -version=VibeDefaultMain -version=Have_vibe_d -version=VibeLibeventDriver -version=Have_foo -version=Have_libevent -version=Have_openssl -version=Have_ddb -Isource -I../../../../home/scmjpg/.dub/packages/vibe-d-master/source -I../../../../home/scmjpg/.dub/packages/libevent-master -I../../../../home/scmjpg/.dub/packages/openssl-master -I../../../../home/scmjpg/.dub/packages/ddb-master/source -Jviews ../../../../home/scmjpg/.dub/packages/ddb-master/source/postgres.d ../../../../home/scmjpg/.dub/packages/ddb-master/source/ddb/db.d source/app.d ../../../../home/scmjpg/.dub/packages/vibe-d-master/source/vibe/appmain.d

But I'm sure I must be missing something. For vibe.d, the module names match the file names exactly. For ddb, the module names do not match, and seem to require manual intervention. Should this work, and do I need to add something to get it work?

Thanks,
Jon.
