Note, this is only for my memo. Environment is Debian lenny.

First, install the following packages.

aptitude install docbook-dsssl docbook-xml jade jadetex libsp1c2 ldp-docbook-dsssl sgml-base sgml-data sgmlspl sp xml-core libsgmls-perl docbook-utils

Down to the docs/ directory, and set system environment as the followings.

setenv JADE_PUB /usr/share/xml/declaration/
setenv LDP_HOME /usr/share/sgml/docbook/stylesheet/dsssl/ldp/

Note: JADE_PUB is for xml.dcl, LDP_HOME is for ldp.dsl.

And run makedocs.pl.
