 What difference does it make so long as it is GPL? 
The source code references v2, so we should ship that or change
the refences back to v1.
As I recall, GPL v2 just contained some clarification of v1
licensing terms.  I think the "mere aggregation" clause was adedd 
in v2, after people wondered whether bundling GPL'd software
would infect a whole distribution.
