 osgEarth supports all kinds of data and comes with lots of examples to help you
 get up and running quickly and easily.
 
-Optional requirements protobuf and rocksdb are recommended for enhanced
-performance. They will be used if detected when osgEarth is built.
+Some optional requirements are recommended for enhanced functionality
+and/or performance. They include:
+    osgQt, poco, protobuf, rocksdb
+
+For all but osgQt, they will be used if detected when osgEarth is built.
+
+In the case of osgQt, the version of Qt that it was built with is relevant.
+If osgQt was built with Qt5, the environment variable OSGQT=5 must be set when
+running the osgEarth SlackBuild i.e.
+    OSGQT=5 sh osgEarth.SlackBuild
+In this case, the qt5 package is also an additional build requirement.
+
+If osgQt was built with Qt4 (the standard for Slackware 14.2), set OSGQT=4 i.e.
+    OSGQT=4 sh osgEarth.SlackBuild
+
+If OSGQT is not set, osgQt support will not be included.
