Unable to define scala language with listings

Question

I'm using the solution here for scala support, but this fails to properly color the scala code, and throws a number of errors when processing lstset - % ! Package keyval Error: breakatwhitespace undefined. Can anyone help me figure out what's wrong with this simple example?

\documentclass[journal]{IEEEtran}
\usepackage{listings}

% "define" Scala
\lstdefinelanguage{scala}{
  morekeywords={abstract,case,catch,class,def,%
    do,else,extends,false,final,finally,%
    for,if,implicit,import,match,mixin,%
    new,null,object,override,package,%
    private,protected,requires,return,sealed,%
    super,this,throw,trait,true,try,%
    type,val,var,while,with,yield},
  otherkeywords={=>,<-,<\%,<:,>:,\#,@},
  sensitive=true,
  morecomment=[l]{//},
  morecomment=[n]{/*}{*/},
  morestring=[b]",
  morestring=[b]',
  morestring=[b]"""
}

\usepackage{color}
\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{mauve}{rgb}{0.58,0,0.82}

\lstset{frame=tb,
  language=scala,
  aboveskip=3mm,
  belowskip=3mm,
  showstringspaces=false,
  columns=flexible,
  basicstyle={\small\ttfamily},
  numbers=none,
  numberstyle=\tiny\color{gray},
  keywordstyle=\color{blue},
  commentstyle=\color{dkgreen},
  stringstyle=\color{mauve},
  frame=single,
  breaklines=true,
  breakatwhitespace=true
  tabsize=3
}
% A number of keyval errors occur here - basically 
% nothing in lstset is recognized. Errors look like:
% ! Package keyval Error:   breakatwhitespace undefined.

\begin{document}

\begin{lstlisting}
object Test {
   def main(args: Array[String]) {
      var a = 0;
      // for loop execution with a range
      for( a <- 1 to 10){
         println( "Value of a: " + a );
      }
   }
}
\end{lstlisting}

\end{document}

EDIT: After adding in \listfiles, here's the file list I see

Answer 1

As noted by Peter in his comments, your TeX distribution seems badly out of date. Time to blow the rust off it, and fire up your package manager.

Also, you're missing a comma after breakatwhitespace=true.

Besides, since October 2013, the listings package comes with a language definition for Scala (in the lstdvrs.dtx file). If you update your TeX distribution, you shouldn't have to redefine that language from scratch in your .tex file in order to use it.
