The above example is for version 5 and below. The packages 
Graphics`Legend` and Graphics`Graphics` are obsolete in version 6. Use 
(and read the documentation) for the new packages PlotLegends` and 
BarCharts`. For instance, the above example should start with

Needs["PlotLegends`"]
Needs["BarCharts`"]
ShowLegend[ ... your graphic primitives here ... ]
