title: Unable to find the JVM during `conda build`
body: <p>I've been trying to build an R package with conda this afternoon and seem to keep running into an issue with rJava. The build process can't seem to find the JVM. I'm running this under OSX 10.12.3 with Java version. Any thoughts on how to help the build process find the JVM?</p>
