Comment (by rjvbertin@…):

 This version introduces a functional build of Qt 5 on OS X 10.6.8 Snow
 Leopard.

 I haven't tried to provide Qt 5.4 on that OS version. I was under the
 impression that building Qt 5.3.2 was still supported on 10.6, but that
 turned out to be wrong and it was cumbersome enough to come up with a
 working build.

 So, port:qt5-mac-devel provides Qt 5.3.2 on OS X 10.6, with an additional
 dependency on port:clang-3.4 or newer. The port also requires that a
 selection be made using `port select` (or through manual symlinks
 `${prefix}/bin/clang` and `${prefix}/bin/clang++`. This is 1) to avoid a
 hard dependency on a specific clang version and 2) because Qt imposes the
 exact compiler choice to all applications built against it, through qmake.
 NB: I haven't yet checked if port:qt5-creator builds against this Qt
 version.

 This qt5-mac-devel version also fixes a series of missing-
 NSAutoreleasePool leaks during startup, through a backported patch from Qt
 5.5
