This is blocking uec-images builds at the moment.

That's added to the maintainer scripts by dh_python2 in the python package.

NOTE: I'm mostly offline for the next 24 hours, so I'm can't immediately deal with this. I suspect reverting the python-defaults changes I pulled from the Debian bzr and rebuilding pyyaml will fix It. Someone like doko should check that.

This bug was fixed in the package python-defaults - 2.6.5-5ubuntu3

---------------
python-defaults (2.6.5-5ubuntu3) maverick; urgency=low

  * Revert update from Debian bzr to fix installability of packages built with
    dh_python2 - the problem of dangling symlinks for packages formerly built
    with python-central will have to be addressed later (LP: #599921):
    - Remove autoscripts/preinst-pycentral-clean
    - Drop reference to autoscripts/preinst-pycentral-clean from dh_python2

No change rebuild of pyyaml is needed once the new python-defaults is published.

[Launchpad Janitor (janitor)]

This bug was fixed in the package pyyaml - 3.09-3build1

---------------
pyyaml (3.09-3build1) maverick; urgency=low

  * No change rebuild for LP: #599921
