Comment (by michaelld@…):

 Here's the error:
 {{{
 :info:build In file included from
 /Volumes/User_Disk/opt/macports/libexec/qt4/include/QtCore/qobject.h:50:
 :info:build
 /Volumes/User_Disk/opt/macports/libexec/qt4/include/QtCore/qlist.h:55:10:
 fatal error: 'initializer_list' file not found
 :info:build #include <initializer_list>
 :info:build          ^
 }}}

 I think that the issue is that qt4-mac was build with support for c++11
 (directly via the +cxx11 variant or even just internally somehow), while
 akonadi is trying to build using c++0x; shouldn't make a difference, but
 clearly it does. "initializer_list" is c++11 or newer.

 What does "port installed qt4-mac" return for you? Did you update to Xcode
 5.1 recently, such as after qt4-mac was last built?
