One way to improve this would be to remove autoselected variants  
during upgrade if they aren't applicable anymore. For example, if you  
have a port installed with +darwin_8 but you're now on Leopard,  
upgrading the port should deselect the darwin_8 variant.

Can you think of other concrete ways we could improve the situation?

I suppose it would be really nice if we had a script you could run  
which would fix everything for you. Rebuild all ports in the right  
order. Of course if you have a lot of ports installed and/or a slow  
machine it could take days to run. Also there might be a few cases  
where it wouldn't work. (I think we still have a few ports which work  
on Tiger but not on Leopard...)

I guess such a script hasn't materialized yet (and the other  
mentioned issues haven't been resolved) because upgrading across  
major OS releases is not something one does often. Generally one does  
it once per major OS release, which is no more frequently than once a  
year. Also, testing such a script could be difficult. The fixes I've  
seen committed to the MacPorts repository recently deal with issues  
one would encounter in normal day-to-day use of MacPorts, so that's  
more important.
