Hello again
I did some additional fiddling with ./bin/mahout :
vagrant@vagrant-ubuntu-trusty-64:~/tl/mahout$ git diff
diff --git a/bin/mahout b/bin/mahout
index 5f54181..0174b31 100755

and got this error when running ./bin/mahout spark-shell

I then changed SPARK_HOME from 0.9.1 to spark-1.0.2 and now it seems to
work fine.
