Error de Smartdiagram al compilar

quiero usar eldiagrama inteligentepero por alguna razón aparece un error:

! Undefined control sequence. \smartdiagram 
code #1#2->\StrCut {#1}{:}\diagramtype \option \IfNoValueTF {#... l.6 ...ram]
{Initiation,Planning,Execution,Closure} The control sequence at the end of 
the top line of your error message was never \def'ed. If you have misspelled 
it (e.g., `\hobx'), type `I' and the correct spelling (e.g., `I\hbox'). 
Otherwise just continue, and I'll forget about whatever was undefined.

Aquí está el código que uso.

\documentclass[12pt]{article}
\usepackage{smartdiagram}

\begin{document}
    \begin{center}
    \smartdiagram[circular diagram]{Initiation,Planning,Execution,Closure}
    \end{center}
\end{document}

No es necesario especificar los paquetes adicionales. Smartdiagram los llamará automáticamente. Su MWE es correcto y compila (Kubuntu 12.10 pero con una "instalación vainilla Latex" completa). Tuve problemas similares antes, con el PPA Texlive2012. Entonces, si realmente estás trabajando con xUbuntu, prueba un "Latex vainilla" completo.
