Thanks Pat! I have followed the instructions on the *README.md* file of the mahout folder:
*You will need to build this using Scala 2.11. Follow these instructions - install Scala 2.11 as your default version* I've done this with the following commands: # scala install wget www.scala-lang.org/files/archive/scala-2.11.7.deb sudo dpkg -i scala-2.11.7.deb # sbt installation echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 642AC823 sudo apt-get update sudo apt-get install sbt * - download this repo: `git clone https://github.com/actionml/mahout.git` <https://github.com/actionml/mahout.git`> - checkout the speedup branch: `git checkout sparse-speedup-13.0` - edit the build script `build-scala-2.11.sh <http://build-scala-2.11.sh>` to put the custom repo where you want it* This file is now: #!/usr/bin/env bash git checkout sparse-speedup-13.0 mvn clean package -DskipTests -Phadoop2 -Dspark.version=2.1.1 -Dscala.version=2.11.11 -Dscala.compat.version=2.11 echo "Make sure to put the custom repo in the right place for your machine!" echo "This location will have to be put into the Universal Recommenders build.sbt" mvn deploy:deploy-file -Durl=file:///home/ubuntu/PredictionIO/apache-predictionio-0.12.0-incubating/PredictionIO-0.12.0-incubating/vendors/.custom-scala-m2/repo/ -Dfile=//home/ubuntu/PredictionIO/apache-predictionio-0.12.0-incubating/PredictionIO-0.12.0-incubating/vendors/mahout/hdfs/target/mahout-hdfs-0.13.0.jar -DgroupId=org.apache.mahout -DartifactId=mahout-hdfs -Dversion=0.13.0 mvn deploy:deploy-file -Durl=file:///home/ubuntu/PredictionIO/apache-predictionio-0.12.0-incubating/PredictionIO-0.12.0-incubating/vendors/.custom-scala-m2/repo/ -Dfile=//home/ubuntu/PredictionIO/apache-predictionio-0.12.0-incubating/PredictionIO-0.12.0-incubating/vendors/mahout/math/target/mahout-math-0.13.0.jar -DgroupId=org.apache.mahout -DartifactId=mahout-math -Dversion=0.13.0 mvn deploy:deploy-file -Durl=file:///home/ubuntu/PredictionIO/apache-predictionio-0.12.0-incubating/PredictionIO-0.12.0-incubating/vendors/.custom-scala-m2/repo/ -Dfile=//home/ubuntu/PredictionIO/apache-predictionio-0.12.0-incubating/PredictionIO-0.12.0-incubating/vendors/mahout/math-scala/target/mahout-math-scala_2.11-0.13.0.jar -DgroupId=org.apache.mahout -DartifactId=mahout-math-scala_2.11 -Dversion=0.13.0 mvn deploy:deploy-file -Durl=file:///home/ubuntu/PredictionIO/apache-predictionio-0.12.0-incubating/PredictionIO-0.12.0-incubating/vendors/.custom-scala-m2/repo/ -Dfile=//home/ubuntu/PredictionIO/apache-predictionio-0.12.0-incubating/PredictionIO-0.12.0-incubating/vendors/mahout/spark/target/mahout-spark_2.11-0.13.0.jar -DgroupId=org.apache.mahout -DartifactId=mahout-spark_2.11 -Dversion=0.13.0 * - execute the build script `build-scala-2.11.sh <http://build-scala-2.11.sh>`* This outputed the following: $ ./build-scala-2.11.sh M build-scala-2.11.sh Already on 'sparse-speedup-13.0' Your branch is up-to-date with 'origin/sparse-speedup-13.0'. ./build-scala-2.11.sh: line 5: mvn: command not found Make sure to put the custom repo in the right place for your machine!

If so, it is not said in the PredictionIO installation instructions nor on the Mahout instructions. I apologise if this is an obvious question for those familiar with the Apache projects, but for an outsider like me it helps when everything (even the most silly details) is spelled out.
