Bug#509939: This problem persists in current testing and unstable

[Jaime Alberto Silva]

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

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:

jaime at inspironjaime2:~$ apt-cache depends ekiga

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:

jaime at inspironjaime2:~$ apt-cache search libpt

jaime at inspironjaime2:~$

So I tought I had to install libpt2.6.1-plugins-v4l2, however I checked
which libraries ekiga is linked against:

jaime at 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)
jaime at 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
jaime at inspironjaime2:~$ dpkg -S /usr/lib/libpt.so.1.10.10
libpt-1.10.10: /usr/lib/libpt.so.1.10.10
jaime at 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?
