scrollkeeper dependency trouble/problem

[Hendrik Visage]

Hi there,
checking for docbook-dtd412-xml... * ERROR * 
 
 Couldn't find the DocBook XML V4.1.2 DTD.  Please make sure that you have the docbook-dtd412-xml package installed. If it is installed, the package probably did not register the DTD in the catalog properly. Consult http://scrollkeeper.sourceforge.net/docbook.shtml for more information.
  
  configure: error: DocBook XML V4.1.2 DTD not present in /etc/xml/catalog. Make sure docbook-dtd412-xml is installed and registers DTD in catalog.
  Creating /var/log/lunar/compile/scrollkeeper-0.3.12.bz2 
  ! Problem detected during "BUILD" !

After "lin docbook-dtd-xml", scrollkeeper lin'd fine.

Greetz
