Build failure with gdc

[lunik1]

I cannot get trash-d to build with gdc.

Reproduction:

Running

dub build --compiler=gdc

gives

     Warning /home/corin/code/d/trash-d/dub.json(5:1): versionName: Key is not a valid member of this section. Did you mean: version, versions, versionFilters
    Starting Performing "debug" build using gdc for x86_64.
