Comment(by vince@…):

 Qt4-mac cannot be built 64-bit with backwards qt3 compatibility, because
 qt3 relied on Carbon, which a 32-bit only API. Therefore, if you want to
 build a 64-bit version, which is the default on SL, you have to select the
 cocoa option (even implicitly), itself incompatible with old qt3 support.
