What happens, as in this instance, the system was originally on 6.1 then 6.3 &
subsequently upgraded to 7.0?
How can I tell whether the versions were installed by the base system or via

I am not clear about how the system distinguishes between gcc installed via
ports and via base system. Indcidentally when did gcc become part of the base
system?
