I read:

it's just out of a default example. it runs fine as a standalone script, but doesn't run in Pd.

dunno what exactly is going wrong, what os are you using ? can you do a import math #or whatever

how do i specify a path to find the module?

pydoc sys.path and: http://www.python.org/doc/current/tut/node8.html#SECTION00811000000000000000...
