    @rawkintrevo I have no problems building this for scala-2.11, with E.g.: `mvn clean install -Dscala.version=2.11.2 -Dscala.compat.version=2.11 -Pviennacl -Phadoop2  -DskipTests`` *note* the scala version is @ 2.11 which I think wee may need to make our cap due to the Breeze vector cap @scala 2.11.2 :
    ```
     [WARNING]  org.scalanlp:breeze_2.11:0.11.2 requires scala version: 2.11.4 
    ```
    ```
