I installed Scala on Ubuntu using the following

sudo apt-get install scala 

~$ which scala
/usr/bin/scala

~$ whereis scala
scala: /usr/bin/scala /usr/bin/X11/scala /usr/share/man/man1/scala.1.gz

~$ scala -version
Scala code runner version 2.9.1 -- Copyright 2002-2011, LAMP/EPFL

My question is what should I put in the variable SCALA_HOME? /usr/bin ?

linux scala ubuntu-12.04
