[PD] OSX, i prefer linux but...

[tdunstan at ihug.com.au]

hi 
i've run into a few problems getting pd to work on my lecturers G4 laptop. i'm 
used to running linux so i don't know where to start. i'd like to convert him 
from MAX but these such issues are not very convincing. 
i can get pd installed and running audio through the core audio but i can't 
seem to get sound running into/out of his Metric Halo Mobile i/o. we tried all 
sorts of things and this is all we got.
i think error -9999 has something to do with it but i don't quite know where to 
start. 
can someone suggest a method or series of flags that may work.
thanks crew.
tom
