[ cross posting from the pd-list - apologies ]

I have made an init.d script to start and stop pd. This works fine in an ssh console. However when the script is invoked by the runlevel startup sequence ie rc5.d/S99puredata, pd complains thus:

pd: error while loading shared libraries: libjack.so.0: cannot open shared object file: No such file or directory

This is peculiar as I'm using alsa and jack isn't installed. I have verified that the alsa devices have initialised before pd is loade. Why is pd looking for jack and failing to open? Is there something weird about using alsa from an rc script rather than the user console?"

Running Ubuntu 12.04 - armhf

thanks for any thoughts!
