Trying to compile siproxd on slack-10.2. both versions .12 and .13.

I have not been able to figure out why My compiles are failing perhaps someone can provide a suggestion.

I seem to be falling over because I have things missing in /usr/share/sgml/docbook/utils-0.6.14/docbook-utils.dsl

Is there anyway to just ignore doing whatever it is that not happening? Complete error set is below:
