Trying to generate Galeon HTML manuals

[Juan Carlos Castro y Castro <jcastro vialink com br>]

I'm using RH 7.2. Back when I used RH 6.2, there was an RPM I downloaded
from <http://people.redhat.com/dcm/software.html> that made it possible
to generate the HTML pages flawlessly. The RH7.1 version doesn't work.
What should I do?

Additional information:

jcastro@jcastro:/usr/src/cvs/galeon>rpm -qa | grep -i docbook
docbook-dtd31-sgml-1.0-10
docbook-style-dsssl-1.64-3

jcastro@jcastro:/usr/src/cvs/galeon>rpm -qa | grep jade
openjade-1.3-17

The error messages:
