I fell in your same issues in the past. You can try and use jhbuild
(you'll need to go through a few docs before succeeding):

http://library.gnome.org/devel/jhbuild/stable/jhbuild-and-gnome.html.en

----

Alternatively, I wrote my own set of scripts. You can take inspiration
from them:

http://gitorious.org/mkgst

please note they're nothing official (personal use only ;) ), so your
degree of success may vary depending on upstream GStreamer
developments / your building environment. The last time I've used them
(the last week) they worked pretty well on a freshly installed Ubuntu.

If you're lucky the only thing you'll have to do in order to build
GStreamer from git is:

cd to the dir containing the mkgst folder
run bash ./mkgst/mkgst.sh

if you're so lucky that build succeeds, in order to set up your shell
to use the newly built environment you'll have to run:

. ./mkgst/setenv.sh

P.S. maybe you'll have to remove some of the -dev packages from your Ubuntu box.

good luck!

Regards
