Years earlier I had a problem with this package
and I think it has something to do with an incompatible
version created somewhere alont the line.
You can check google, I don't remember exactly
what the problem was and it looks like it eventually
resolved when I updated everything. 

I expected some issues with this and created a bunch
of places to prepend search paths for locations to
dump candidate packages that may fix problems with 
current ones lol.  Quickly grepping my directories
and scripts though I'm not sure if everything did
finally work without a lot of kluges..
