I read:
Here's the output of verbose:
Pd version 0.37.1 devel compiled 09:52:15 Jun 17 2004 port 5403 Waiting for connection request... "/Applications/Utilities/Wish Shell.app/Contents/MacOS/Wish Shell" ../lib/pd/bin/pd.tk 5403 setting pd_guidir to '.'
looks like it's running with the wrong pd-gui / pd.tk (I'm no os x expert so the directory structure and install procedures are pretty much greek to me.
I can reproduce a similar result on linux by explicitly supplying a wrong pd-gui version with the -guicmd switch.
