+<li><strong>How do I install the RPMs on a Redhat linux system?</strong>
+
+<P>The problem is that the default version of python for Redhat 7.x is
+1.5.x, and rdiff-backup requires python >= 2.2.  Redhat/rawhide
+provides python 2.2 RPMs, but they are packaged under the "python2"
+name.
+
+<P>So, if you are running Redhat 7.x:
+
+<ol>
+<li>Make sure the python2 >= 2.2 package is installed,
+leaving python 1.5 the way it is
+<li>Install the rdiff-backup RPM, using --nodeps if it only complains
+    about python 2.2 missing.
+<li>Edit the first line of /usr/bin/rdiff-backup so it says<pre>
+#!/usr/bin/env python2
+</pre>
+so "python2" gets run instead of "python".
+</ol>
+
+<P>You can also upgrade using a non-Redhat python 2.2 RPM and avoid
+the above steps (this is what I did).  Because of all the dependencies
+it is usually easier to use source RPMs for this.
+</li>
