Im trying to build a project with elasticsearch-d on OSX and am getting the following error:

Target vibe-d 0.7.23 is up to date. Use --force to rebuild.
Target elasticsearch-d 1.0.0-beta.1 is up to date. Use --force to rebuild.
Building test2 ~master configuration "application", build type debug. 
Compiling using dmd...

Error executing command build: dmd failed with exit code 1.

I created a vibe project and it ran just fine. Note: this is my first time really trying to load a package in from DUB. I added

"dependencies": {
"elasticsearch-d": "~>1.0.0-beta.1"

}

to dependencies and ran dub build. Im new to dub so not sure if I might have missed something.
