Missing gstreamer and farsight dependencies in pidgin

Question

I am trying to compile pidgin and getting the following error on runing the configure script(see below). This is the newest unstable version of Debian with the 2.6.38-2-686 kernel. It's not clear for me what dependency I am missing. Any help appreciated.

    checking for GSTREAMER... yes
    checking for gst_registry_fork_set_enabled in -lgstreamer-0.10... yes
    checking for GSTINTERFACES... no
    checking for FARSIGHT... yes
    configure: error: 
    Dependencies for voice/video were not met.
    Install the necessary gstreamer and farsight packages first.
    Or use --disable-vv if you do not need voice/video support.

dpkg --get-selectons

Answer 1

I looked in the configure.ac file of pidgin to see exactly what it is looking for to determine if these dependencies are present. It's using pkg-config to check for dependencies, so it's pretty easy to determine which file it is looking for and then which packages provide those files. The packages you'll need to install (from debian unstable) are:

libgstreamer-plugins-base0.10-dev
libgstfarsight0.10-dev

To figure this out I did the following:

1. Open configure.ac and search for GSTINTERFACES / FARSIGHT (from error message)
2. I noticed the calls to PKG_CHECK_MODULES, which accepts a parameter that corresponds to the name of a file in /usr/lib/pkgconfig if the package is installed. For gstreamer-interfaces it was gstreamer-interfaces-0.10 and for farsight it was farsight2-0.10.
3. I went to http://packages.debian.org and searched for packages which contain files named like these files. That turned up these two packages.
