Comment (by jeremyhu@…):

 {{{
 :info:build /opt/local/include/sys/stat.h:75:10: fatal error:
 'Availability.h' file not found
 :info:build #include <Availability.h>
 }}}

 Remove libc-headers, CarbonHeaders, and all those other ports that
 conflict with system headers and try again.

 Also, please file tickets against whatever port depended on those ports,
 so they can fix the real issue rather than forcing users to break their
 system with broken ports that don't match system libraries.

 I will not support these configurations.
