After much playing around, I managed to build a pd-extended 64bit .deb for Ubuntu Intrepid.
I put all of the steps on the pd-wiki: http://puredata.info/docs/developer/BuildingPdExtended64bitUbuntuIntrepid
It's not a true pd-extended as the 0.41 version seems to still have the table bug, but now I can use my new computer for pd-age.
