I don't see quite why this is happening, but openldap20-client
is in the dependencies list and it does install ldap.h. I suspect that
this is tied to the separation of openLDAP into client and server
packages.

In any case, install openldap20-client and gnomemeeting should build.

At this time FreeBSD is lacking the framework for any standardized
video support which would be required for anything like standard
video support. The only real video available is with the BKTR
driver. This chip (BrooKTRee) is found in the majority of the video
for windows boards including those from Hauppauge and Pinnacle. I use
a cheap ($25 US) WinTV-Go card and it works.

You can use GnomeMeeting without a video card to participate in
meetings. You will have full audio support and will receive video. You
only lack video send capability.

I have found one problem with pwlib (upon which GnomeMeeting is built)
in that it will re-read the same video frame over and over again,
eating up all available CPU IF THERE IS NO MOVEMENT. 

This is a problem with the video4bsd module and can be worked around
by adding a usleep at the start of the
PVideoInputDevice::GetFrameDataNoDelay routine in
/usr/ports/devel/pwlib/work/pwlib/src/ptlib/unix/video4bsd.cxx.
  (void) usleep(33000); /* Don't keep reading the same frame! */

This is a ugly, ugly kludge and I can see some better ways to fix
this, but I simply have not had time to look do this. (Volunteers are
welcome!)

Oh. I am not the maintainer, either. Just a regular GnomeMeeting user.
