I've never encountered this error, so I'm just guessing here. However, CPAN will install the latest stable version of the module, so if this is an error caused by improperly installed source or an error in the latest/greatest modification to the module, CPAN ought to give you a working copy. Also, if you've never used the CPAN module before, don't be afraid to throw the -force arg in there if things don't go right the first time. Sometimes CPAN just doesn't know where to find the module dependencies.
