 While building kdelibs4, I get this error

 {{{
 -- Building kdelibs...
 CMake Error at cmake/modules/FindKDE4Internal.cmake:1053 (message):
   Qt compiled without support for -fvisibility=hidden.  This will break
   plugins and linking of some applications.  Please fix your Qt
 installation.
 Call Stack (most recent call first):
   CMakeLists.txt:33 (find_package)


 -- Configuring incomplete, errors occurred!
 }}}

 I get an identical error with kdebase4, kdepimlibs4 and phonon

 I have tried rebuilding qt4-mac to no avail.
