My mistake. git-core depends on perl5, like I said, but perl5 depends  
on perl5.8. I had thought perl5 could make use of either perl5.8 or  
perl5.10, whichever was already installed, but I was wrong. In that  
case, there isn't a way to have MacPorts use perl5.10.

Marcus, what is the purpose of perl5, then? :) Why did we spend all  
this effort converting ports from depending on perl5.8 to depending  
on perl5?

http://trac.macports.org/ticket/16830 is the ticket about perl5,  
which is very lengthy and I don't feel like like reading through it  
all now. The last comments say we're waiting on perl 5.10.1 to be  
released, which still hasn't happened.
