Just wanted to note that I have a similar problem installing gnome-doc-utils
(as well as some other software), see bug 157839, but I do have
docbook-xml-dtd-4.4 installed.  To be precise, I have both
app-text/docbook-xml-dtd-4.1.2-r6 
app-text/docbook-xml-dtd-4.4-r1
installed.

Please attach the complete emerge log (and try to provide all relevant
information when you open new bugs; reports that just say "foobar fails to
build" are rarely useful).

I tried unmerging docbook-xml-dtd-4.4 on a testing system and then emerging
gnome-doc-utils-0.8.0, and even though it shows a warning (it does look like a
missing dep), the emerge doesn't fail.

To reproduce it, I had to remove refrences to docbook-xml-dtd-4.4 from
/etc/xml/docbook shown below:

  <public publicId="-//OASIS//ELEMENTS DocBook XML Information Pool V4.4//EN" u
ri="file:///usr/share/sgml/docbook/xml-dtd-4.4/dbpoolx.mod"/>
  <public publicId="-//OASIS//DTD DocBook XML V4.4//EN" uri="file:///usr/share/
sgml/docbook/xml-dtd-4.4/docbookx.dtd"/>
  <public publicId="-//OASIS//ENTITIES DocBook XML Character Entities V4.4//EN"
 uri="file:///usr/share/sgml/docbook/xml-dtd-4.4/dbcentx.mod"/>
  <public publicId="-//OASIS//ENTITIES DocBook XML Notations V4.4//EN" uri="fil
e:///usr/share/sgml/docbook/xml-dtd-4.4/dbnotnx.mod"/>
  <public publicId="-//OASIS//ENTITIES DocBook XML Additional General Entities 
V4.4//EN" uri="file:///usr/share/sgml/docbook/xml-dtd-4.4/dbgenent.mod"/>
  <public publicId="-//OASIS//ELEMENTS DocBook XML Document Hierarchy V4.4//EN"
 uri="file:///usr/share/sgml/docbook/xml-dtd-4.4/dbhierx.mod"/>
  <public publicId="-//OASIS//DTD DocBook XML CALS Table Model V4.4//EN" uri="f
ile:///usr/share/sgml/docbook/xml-dtd-4.4/calstblx.dtd"/>
  <rewriteSystem systemIdStartString="http://www.oasis-open.org/docbook/xml/4.4
" rewritePrefix="file:///usr/share/sgml/docbook/xml-dtd-4.4"/>
  <rewriteURI uriStartString="http://www.oasis-open.org/docbook/xml/4.4" rewrit
ePrefix="file:///usr/share/sgml/docbook/xml-dtd-4.4"/>

Emerge fails with errors from xsltproc:
error : Operation in progress
http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd:123: warning: failed to
load external entity "http://www.oasis-open.org/docbook/xml/4.4/dbcentx.mod"
%dbcent;
        ^
Entity: line 1: 
 %dbcent; 
         ^

These take really long time to show up, so I'll attach complete log if it is
still needed.

I've added the missing dependency to gnome-doc-utils' ebuild. Don't forget to
re-emerge docbook-xml-dtd to bring your XML catalog to a sane state again.

Thanks.
