This problem is still present in the current testing and unstable versions

I expended several hours in the last days trying to make my Dell Inspiron
1420's uvcvideo integrated webcam (05a9:2640 OmniVision OV2640) work with
ekiga.
I had checked the bug reports but only for uvcvideo, never for v4l2. Late
last night I figure it out that Ekiga didn't had support for V4L2, by
watching at Ekiga's dependencies I guessed that I must install libpt's v4l2
plugin:

However when I tried to install libpt2.4.2-plugins-v4l2 I got an error
saying that the package was not available. So I made a search for libpt:

So I tought I had to install libpt2.6.1-plugins-v4l2, however I checked
which libraries ekiga is linked against:
ja...@inspironjaime2:~$ ldd /usr/bin/ekiga | grep libpt
libpt.so.1.10.10 => /usr/lib/libpt.so.1.10.10 (0x00007fef750c1000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00007fef73f28000)
ja...@inspironjaime2:~$ ls -l /usr/lib/libpt.so.1.10.10
-rw-r--r-- 1 root root 4033536 2008-04-02 00:58 /usr/lib/libpt.so.1.10.10
ja...@inspironjaime2:~$ dpkg -S /usr/lib/libpt.so.1.10.10
libpt-1.10.10: /usr/lib/libpt.so.1.10.10
ja...@inspironjaime2:~$
And I found that the correct package is libpt-1.10.10-plugins-v4l2. After
installing it the camera worked perfectly.
All this brings me to a question: Why ekiga's dependencies list libpt2.4.2*
but you must use libpt-1.10.10* ?
Can you imagine a regular desktop user trying to figure this out?
I understand your frustration and time spent.
The error above is that, I suppose, apt-cache depends ekiga looks at the
experimental version of ekiga, while you have unstable version installed.
As for v4l2, in the next build (I hope in one week), v4l2 will be the
first choice, before v4l, so it will be installed by default.
Maybe it is better to have all plugins in one package, anyway the
plugins have between 10kB and 100kB (from memory).
