 Builing a RPM package from SVN
-===============================
+==============================
 You may build the package from a svn checkout. Follow the instructions
 at http://varnish.projects.linpro.no/wiki/Repository to get the
 source. Then enter the trunk directory and edit
 varnish-cache/redhat/varnish.spec. At least bump the version and/or
-release numbers. Then use something like this to build the rpm package:
+release numbers, and uncomment the autogen call. You need to install
+the autoconf and automake packages. Then use something like this to
+build the rpm package:
 
 #!/bin/bash
 VERSION=$( awk ' /^Version:/ { print $2 } ' varnish-cache/redhat/varnish.spec )
