Good news!
Using Debian to compile pdgst.pd_linux = working!
I am now able to use gstreamer inside pd to stream to justin.tv: http://www.youtube.com/watch?v=SD6s2xeMB1w
Next thing is to stream something from gem / pix, but i get this error: /usr/lib/pd/extra/pix_pix2gst.pd_linux: /usr/lib/pd/extra/pix_pix2gst.pd_linux: undefined symbol: _ZN9CPPExternaSERKS_
I really need help on this one. Thanks
