Comment(by ryandesign@…):

 At present, we know that qt4-mac cannot be built while kdelibs3, kdelibs4,
 libevent or xmlrpcxx are active. Deactivate any of these ports that are
 installed before attempting to build qt4-mac. You can reactivate them
 afterward.

 The conflicts keyword used in the qt4-mac port to indicate this does not
 adequately encompass this situation; we need a second type of conflicts
 keyword to be implemented by MacPorts base to automate the detection of
 this problem. See [http://lists.macosforge.org/pipermail/macports-
 users/2010-March/019423.html this mailing list discussion].
