I'm trying to add the flac bindings from deimos to the dub registry, and I get this lovely message:

500 - Internal Server Error

My best guess would be that there's something wrong with flac's package.json file, but if so, I can't figure out what it is:

{
    "name": "flac",
    "description": "Deimos bindings for flac, a free lossless audio codec library",
    "homepage": "http://xiph.org/flac/",
    "importPaths": ["."],
    "targetType": "sourceLibrary",
    "license": "BSD",
    "libs" : ["flac"]
}
