Hi, Tarun Kumar Mall filed this patch (as a diff of a diff no less) in a bug[0] against the Debian package of ivtv-utils based on a report in LaunchPad[1]. Details are pretty much non-existent but I infer that it has something to do with Ubuntu Natty using gold instead of the tradition GNU ld and that the underlying issue is to do with the ordering of the .o files and the libraries on the link line, specifically libraries need to come second.
It looks plausible enough to me. Ian.
