+In the text below I'll use WXDIR with environment variable syntax
+(either $WXDIR or %WXDIR%) to refer to the top level directory were
+your wxWidgerts and wxPython sources are located. It will equate to
+whereever you checked out the wxWidgets module from CVS, or untarred
+the wxPythonSrc tarball to. You can either substitute the $WXDIR text
+below with your actual dir, or set the value in the environment and
+use it just like you see it below.
+
+If you run into what appears to be compatibility issues between
+wxWidgets and wxPython while building wxPython, be sure you are using
+the wxWidgets sources included with the wxPythonSrc tarball or the CVS
+snapshot, and not a previously installed version or a version
+installed from one of the standard wxWidgets installers. With the
+"unstable" releases (have a odd-numbered minor release value, where
+the APIs are allowed to change) there are often significant
+differences between the W.X.Y release of wxWidgets and the W.X.Y.Z
+release of wxPython.
