Debian Farstream dependencies

I am having trouble getting pidgin to build from source. Running the ./autogen.sh I fail on not finding FARSTREAM but I have that package installed. blubee@naibed:~/Development/pidgin-main$ sudo aptitude search farstream i A gir1.2-farstream-0.1 - Audio/Video communications framework: GObject-Introspection i A gir1.2-farstream-0.2 - Audio/Video communications framework: GObject-Introspection i A libfarstream-0.1-0 - Audio/Video communications framework: core library p libfarstream-0.1-dbg - Audio/Video communications framework: debugging symbols i libfarstream-0.1-dev - Audio/Video communications framework: development files p libfarstream-0.1-doc - Audio/Video communications framework: documentation i A libfarstream-0.2-2 - Audio/Video communications framework: core library p libfarstream-0.2-dbg - Audio/Video communications framework: debugging symbols i libfarstream-0.2-dev - Audio/Video communications framework: development files p libfarstream-0.2-doc - Audio/Video communications framework: documentation i libtelepathy-farstream-dev - Glue library between telepathy and farstream (development files) p libtelepathy-farstream-doc - Glue library between telepathy and farstream (documentation) i A libtelepathy-farstream3 - Glue library between telepathy and farstream p libtelepathy-farstream3-dbg - Glue library between telepathy and farstream (debug symbols) p libtelepathy-qt4-farstream2 - Telepathy/Farsight integration - Qt 4 library p python-farstream - Audio/Video communications framework: Python bindings v python2.7-farstream - as you can see from my aptitude search i've installed everything debian recommends for farstream but I still get the build error. checking for JSON... yes checking for ZLIB... yes checking for gconftool-2... /usr/bin/gconftool-2 Using config source xml:merged:/etc/gconf/gconf.xml.defaults for schema installation Using $(sysconfdir)/gconf/schemas as install directory for schema files checking for GSTREAMER... yes checking for GSTVIDEO... yes checking for FARSTREAM... no configure: error: Dependencies for voice/video were not met. Install the necessary gstreamer and farstream packages first. Or use --disable-vv if you do not need voice/video support. also I have already installed all the gstreamer plugins i gstreamer1.0-plugins-bad - GStreamer plugins from the "bad" set i gstreamer1.0-plugins-bad-dbg - GStreamer plugins from the "bad" set (debug symbols) i gstreamer1.0-plugins-bad-doc - GStreamer documentation for plugins from the "bad" set i gstreamer1.0-plugins-base - GStreamer plugins from the "base" set i gstreamer1.0-plugins-base-apps - GStreamer helper programs from the "base" set i gstreamer1.0-plugins-base-dbg - GStreamer plugins from the "base" set i gstreamer1.0-plugins-base-doc - GStreamer documentation for plugins from the "base" set i gstreamer1.0-plugins-good - GStreamer plugins from the "good" set i gstreamer1.0-plugins-good-dbg - GStreamer plugins from the "good" set i gstreamer1.0-plugins-good-doc - GStreamer documentation for plugins from the "good" set i gstreamer1.0-plugins-ugly - GStreamer plugins from the "ugly" set i gstreamer1.0-plugins-ugly-dbg - GStreamer plugins from the "ugly" set (debug symbols) i gstreamer1.0-plugins-ugly-doc - GStreamer documentation for plugins from the "ugly" set I've been doing apt-cache and aptitude search but can't figure out what's missing. What am I missing?
