Adding a "docbook-xml" build dependency fixes this. I'll provide a debdiff to fix this for Gutsy.
In the Ubuntu build system, the build gets interrupted by: -------------------------- XMLLINT ./usermanual.xml error : Operation in progress ./usermanual.xml:7: warning: failed to load external entity "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd" "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd"> ^ error : Operation in progress warning: failed to load external entity "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd" validity error : Could not load the external subset "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd" Document ./usermanual.xml does not validate make[1]: *** [lint] Error 3 make[1]: Leaving directory `/build/buildd/bitbake-1.8.2/doc/manual' ERROR: Unable to generate html documentation. --------------------------
I guess, that when using pbuilder (and with the Debian build system) the external entity gets loaded, but the Ubuntu build system does not allow this.
