+    When using Gentoo setting up the tool chain is relatively easy:
+<programlisting>
+sudo emerge -av app-text/openjade app-text/docbook-sgml-dtd:4.2 app-text/docbook-dsssl-stylesheets app-text/docbook-xsl-stylesheets libxslt
+</programlisting>
+    Since Gentoo often supports different versions of a package to be
+    installed you have to tell the PostgreSQL build environment where the
+    Docbook DTD is located:
+<programlisting>
+cd /path/to/postgresql/sources/doc
+make DOCBOOKSTYLE=/usr/share/sgml/docbook/sgml-dtd-4.2
