@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
```
```
