Graph::Base is seriously broken.  I urge anyone who's using it to check
the bug list at 

The developer, Jarkko Hietaniemi, is well aware of the problems and is
working on a rewrite.  In the meantime, I have a very simple graph
package that I'm happy to share.  It handles undirected, unlabelled
graphs only.  It provides depth and breadth first search, all pairs
shortest path, enumeration of all paths in a graph, as well as the
