Yes, 4.8.4_3 was installed normally without needing to change anything.

Does Apple’s GCC 4.0 actually support C blocks? I thought they were a Clang extension.
Unless you’re suggesting that lack of support shouldn’t actually be a failure state.

Should be fixed in r102936. Please someone confirm, and then I'll close this ticket.

Anyone who experienced the problem, then ran selfupdate and tried again without manually cleaning, would still fail, because r102936 did not change the Portfile, and therefore MacPorts wouldn't know that it should clean before trying again. So I made a small unrelated change to the Portfile in r102951 to trigger the automatic clean.

Yeah; I forgot that "minor" detail; thanks for dealing with it!

After an unsuccessful attempt, apparently due to my computer was overworking, the port has been correctly installed. Problem solved. Another victory. Congrats. Thenk you very much :)
I take it that compiling using Apple's GCC 4.0 worked OK on 4.8.4_3 before the change I made to checking for ObjC blocks? If that's the case, then I need to figure out a better way to test for this condition.
