hi all,
The documentation for how to install Pd on Mac OSX (on http://www.crca.ucsd.edu/~msp/Pd_documentation/index.htm) was out of date with respect to the new Tcl releases... I've fixed this and uploaded to the HTML documentation, but if you've downloaded Pd for OSX, please use the above link and don't refer to your local HTML documentation for instructions.
