Comment (by Ionic):

 Carbon isn't complete dead, as jmr pointed out. Apple's Frameworks might
 happily use it still today (and do so.)

 I think we boiled the issue down to **something** installing a file as
 `/usr/local/include/MacTypes.h` and thus breaking `CoreServices`. Anyone
 affected by this bug - could you please check if such a file exists on
 your system? If it does, please attach it to trac so that I can take a
 look at it and maybe find out what installed it in the first place. Must
 be some third-party software.
