I keep getting errors with this:

(DMD 2.063, OSX 10.7)

{
"description": "An example project skeleton",
"authors": [
    "Your Name"
],
"subConfigurations": {"vibe-d": "libevent"},
"dependencies": {
    "vibe-d": "==0.7.15"
},
"homepage": "http://example.org",
"name": "test_http_hi",
"copyright": "Copyright © 2000, Your Name"
}

It complains that "No event driver is available. Please specify a -version=Vibe*Driver..., even though it's specified in the package.json.

When I try the command line with --config=libevent:

Error: opApply may only be called on objects, not Array.

How can I get vibe.d to work?
Thanks,
NMS
