port cat always uses the copy in the ports tree. That might be the same 
as one or neither of the copies in the registry.

Sure. I don't think we have code to roll back the copying of the 
Portfile to the registry directory if we get interrupted by a signal 
mid-install.

Hard to say how right or wrong this is without also seeing what 'port 
installed bison' reports, but in general these files are supposed to be 
deleted when the last port that references them is uninstalled.
