Comment (by bernard.j.kelly@…):

 Hi Jeremy. I just did the following:

 {{{
 port uninstall CarbonHeaders
 port uninstall clang-3.3
 port selfupdate
 port upgrade outdated
 port install clang-3.3 +python27 +assertions
 }}}

 ... and hit the same install error. I'll attach the error log, but to give
 some "reduced case" as you suggest sounds like I'd have to get a clean
 machine with no other ports installed, which I'm afraid I cannot do. Do
 you have any suggestion for what I could supply to show the current
 configuration?
