xml2-config is dead, long live pkg-config
The Debian unstable builds are failing with:
checking for libxml2 library... configure: error: xml2-config returns badness
cd build && tail -v -n \+0 config.log
and while in fact it's an error, the xml2-config
is going to be obsoleted soon, and we should try using pkg-config
to find libxml2 first.
