Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.


Relevant part (hopefully):
> checking for dot... /usr/bin/dot
> checking for compatible dot version (>= 2.26.0)... yes 2.43.0
> checking for a2x... /usr/bin/a2x
> checking manpage creation with a2x... no
> configure: WARNING: ==> You want to build the manpages with a2x, but manpage formatting does not work!
> configure: error: ==> Install the packages that contains the docbook DTD and XSL stylesheets (presumably docbook, docbook-xml) or disable the build of the manpages using '--disable-manpages'.
