+Subject: [PATCH 4/6] Ensure that the correct version of Qt is always used.
+
+With the introduction qt-4.8.6, Qt binaries were moved from /usr/bin to
+/usr/$(get_libdir)/qt4/bin, leaving behind in their place symlinks to qtchooser.
+
+There is no guarantee to which version of Qt these symlinks might point, so it
+is necessary to find the correct version explicitly.
+
+Once qmake is found, it is queried for the correct location of all other items.
+
+Bug: https://bugs.gentoo.org/547222
