A new version of DDT - D Development tools is out:

https://github.com/bruno-medeiros/DDT/releases/tag/Release_0.10.0

The major new feature is DUB support (there are breaking changes, please read the changelog and updated User Guide sections for more info).

A lot of the UI has been cleaned up as well, removing inoperative functionality, changing the references to DLTK concepts (such as "interpreters" or "script"), etc.

PS: Thanks to Sönke for bringing DUB into an existence, this tool is awesome! (this could even be an understatement... a package management and build tool is crucial for D's success!)

I ran into this Kepler bug trying to update.  The work-around is stated, which involves renaming your eclipse.exe. Worked for me.
