Thanks -- kludgy, but it works.  Here's the culprit:


sudo apt-get install libdc1394-13-dev libgsm1-dev libtheora-dev

libdc1394-13-dev is already the newest version.
libgsm1-dev is already the newest version.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  libtheora-dev: Depends: libtheora0 (= 0.0.0.alpha5-0ubuntu2) but 1.0alpha3-0.0 is to be installed
E: Broken packages


OK, so given that, it appears there's an inconsistency in the
Ubuntu Dapper repos, since I can't remove libtheora0 -- it's
required by everything, including deps of 'ubuntu-desktop':

: jm 37...; sudo apt-get remove libtheora0

Anyone got any tips at this stage?  How can I install the ffmpeg
build-deps?
