Comment 2 for bug 1056820

Unfortunately, libxml2-2.9.0+dfsg1-2 from experimental does not build on Quantal (see attached log). Also, libxml2 has a lot of reverse-depends so the new version of that will need an FFe and I'd feel more confident if we did a test rebuild of its rdeps to make sure the new version doesn't break anything.

Alternatively (and I will explore this next), since the 2.8.0 ftbfs is due to a test failure, perhaps we can fix, workaround, or ignore that test for Quantal.
