Resolved using
/**

    *
    * @var  string
    */
    var $dotCommand = 'e:\\intranet\\att\\graphviz\\bin\\dot';

To which manual page are you referring? Or did you report a bug in the example code that comes with the package?

Assigning to Volker who's the lead on this package.

This is not actually a bug.  This just occurs when the GraphViz package in not installed, or is installed and not in the path.

Note that to use this module you need to install the GraphViz package on you system.

You can get it from http://www.graphviz.org/

Hope this helps...

Sorry, but your problem does not imply a bug in PEAR itself.  For a
list of more appropriate places to ask for help using PEAR, please
visit http://pear.php.net/support/ as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PEAR.
