Hello,

I have the following set of laptops which are all running the same SVN
revision of the ports r315646 and only the last one was updated today to
a new base/head revision r250588:

| name         | kernel   | date         | ports (r or date) | remarks
+--------------+----------+--------------+-------------------+--------
| Aurora       | r235646  | May 19, 2012 | r315646 20130401  |
| tiny         | r235646  | May 19, 2012 | r315646 20130401  | cloned Aurora
| Perlach      | r235646  | May 19, 2012 | r315646 20130401  | cloned Aurora
| La-Habana    | r250588  | May 13, 2013 | r315646 20130401  |

the ports have been compiled on Aurora and moved via pkg_create(8) to
the other hosts (around 1200 ports); on 'La-Habana' where the new kernel
is running I have had to rebuild only cuse4bsd-kmod-0.1.27, because it's
a kmod and depends on the sources of the running kernel; on all systems
of r235646, Skype is fine with the cams I have, on r250588 my cams are
working with pwcview(1) but not with Skype.

What can we do to debug this?

We should move this thread to freebsd-multimedia only, I suggest.

Thanks

	matthias
