im running ubuntu feisty 7.04, libquicktime plugins are in standard

danja at t43:~$ cat /etc/debian_version

danja at t43:~$ ls /usr/local/lib/libquicktime/
lqt_audiocodec.la  lqt_faac.la   lqt_ffmpeg.la  lqt_mjpeg.la
lqt_png.la     lqt_videocodec.la
lqt_audiocodec.so  lqt_faac.so   lqt_ffmpeg.so  lqt_mjpeg.so
lqt_png.so     lqt_videocodec.so
lqt_dv.la          lqt_faad2.la  lqt_lame.la    lqt_opendivx.la
lqt_rtjpeg.la  lqt_vorbis.la
lqt_dv.so          lqt_faad2.so  lqt_lame.so    lqt_opendivx.so
lqt_rtjpeg.so  lqt_vorbis.so

so i just did this and noting has changed...

danja at t43:~$ export LIBQUICKTIME_PLUGIN_DIR=/usr/local/lib/libquicktime
danja at t43:~$ pd
tk scaling is 1.22249724972
quicktime_delete_vcodec_stub called

the last line is what PD spits out when i try opening my mjpeg.
mjpeg i make using MEncoder 2:1.0~rc1-0ubuntu9.1
like this:
for i in $( ls ); do mencoder mf://$i/*.jpg -mf fps=6 -o $i.avi -ovc
lavc -lavcopts vcodec=mjpeg; done

where else to look?
