ok, both locally and on the Ubuntu buildds in a wily environment, I get another
build failure.


however, this is with a rebuilt boost1.58, libsigc++2.0, libapt-pkg-dev,
xapian-core, cppunit.

xapian and boost were uploaded today, bug reports for libsigc++ and cppunit
exist (if maintainers don't reply, maybe you could coordinate these
transitions?). Michael Vogt provided me with an update for apt which I should
upload, coordinating with David.

So I think unstable is not yet ready to do this rebuild.
