Comment(by ryandesign@…):

 Yes it would be great if ports would specifically check for Xcode 3.1, if
 they indeed require that. Obviously that check would only be done on
 Leopard. See the cairo port (e.g. r39247) for an example of how this can
 be done, given the lack of support in MacPorts base for checking the Xcode
 version.
