Comment (by nicos@…):

 Thanks for the report, I was not aware that this error was so widespread.
 I however doubt it is solely due to changes in the cmake portgroup,
 because I experienced a similar error 3 weeks ago with kdevelop, but I
 thought at the time it was isolated. It happened previously with 10.8, and
 I could solve this particular case by ensuring that the clang compiler was
 recent enough (>= 3.3).

 On another note, this message seems flawed, because for what I searched
 before, even when qt4-mac is built with -fvisibility-hidden (and it is by
 default), this error was popping out. For confirmation, does your
 ${prefix}/include/Qt/qglobal.h file defines QT_VISIBILITY_AVAILABLE ? If
 yes, that means that the test does not work.

 We would need to either correct the compilation line in the test, or just
 remove it if we are sure that qt4-mac always builds with -fvisibility-
 hidden, but that seems to be the case (I did not check thoroughly yet).
