gridflow.pd_darwin is built from bridge/puredata.c

bridge/puredata.c already contains #undef, but there's a // in front of it 
to disable, because I didn't remember what it was for, and it was 
preventing GridFlow from working with Ruby 1.8 again. However, I've 
redefined T_DATA properly, so now it could be #undef'ed again, for the 
benefit of OSX users.

This is because T_DATA is defined in both Ruby and OSX's OpenTransport 
with different meanings and purposes; and because the definitions of 
T_DATA in Ruby 1.8 and Ruby 1.9 differ as well.

*strangely*, when I'm not #undefing T_DATA and still #defining it again, 
g++ doesn't give me any warning, even though it *is* a duplicate 
definition that it would normally warn me about! (anyone understands

I don't recommend modifying system files unless you really know what 
you're doing, but if you really know what you're doing then modifying 
bridge/puredata.c is a lot easier.
