I think you meant to say LD_LIBRARY_PATH=./lib

Also, since I'm pretty sure that this is all caused by vdpau, in order for it
to use the libvdpau_nouveau.so that you generated, you need to have a libvdpau
in that *same* lib directory. Otherwise it'll get loaded from a fixed path.
(You can run strace -f -e open to confirm.)

Mind testing out http://patchwork.freedesktop.org/patch/18063/ ? (Note, again,
make _sure_ that the 'new' version of libvdpau_nouveau.so is being loaded, not
the old one.)
