[oe] Building Gstreamer from GIT

[srinredplano SP]

Hi All,
I am trying to build Gstreamer from GIT ( using branch 0.10.23 ) .But
I am not able to run autogen.sh due to missing .git  directory .

Can any one let me know why the . git is  getting erased and what I
should do to stop getting   that erased. (I am verymuch new to Git
(though I have build Gstreamer using svn)o build Gstreamer using GIt
Pointers for building Gstreamer using GIT  would be helpful.

Here is my recipe http://pastebin.com/tz6dsZmV . Thanks in Advance
