Right, and relatedly, you would thus not override the extract phase  
with "extract {}" (which there is never a reason to do, and which in  
the future lint will complain about).

Perhaps.

It can be done either way.

The same can be said of master_sites.

In the mysql5-devel port, for example, there is the innodb_plugin  
variant which downloads an additional file from a different location.  
In mysql5-devel, I have the master_sites all defined in the global  
part of the portfile, but append the checksums in the variant. I  
could have put both in the global section, or both in the variant.  
All that matters is that only in the variant is the new distfile  
appended to the distfiles variable.
