Yes, I pulled from SVN:

svn export https://opalvoip.svn.sourceforge.net/svnroot/opalvoip/ptlib/branches/v2_10 ptlib
svn export https://opalvoip.svn.sourceforge.net/svnroot/opalvoip/opal/branches/v3_10 opal

and ekiga from git;

Thanks! This fixed the problem. And after fixing a bug in PTlib
concerning the detection of /dev/video0 in FreeBSD, which I've posted
already in 2008 :-( the video is detected fine. Also the call to the
echo service of ekiga works nicely. Concerning the detection of the
audio device, there is another bug: it only sees and uses /dev/dsp0 but
not /dev/dsp1 (even not when one sets this hardcoded with gconf-editor);
I will investigate this later and provide a patch; the patch for the
/dev/video0 in FreeBSD is attached;

Maybe someone could commit this to not have to look for it again in two
years :-) 

Thanks for your help, Eugen!
