Suggestion regarding config of ports

[Pierre-Luc Drouin]

Hi,

I think it would be nice if there was a way for port maintainers to 
specify if a port needs to be reconfigured. For example, today (May 6, 
2006) there has been an update of port lang/php4 and there is a new 
option to choose if the apache module has to be compiled or not. If 
there was a flag in the port system that allowed to force configuration 
of the port if the installed version is less than a certain value, users 
would have seen immediately that they had to check that new "Apache 
module" option to have that module reinstalled...
