GridFlow 0.8.0 and later all have "make test" broken. If you can get as 
far as the "expect_convolution_matrix" error, you're ok. (Sorry)

That one is normal on G5 computers (it's an option designed to support K8 
processors).

the directory leading to m_pd.h must be found in the CPLUS_INCLUDE_PATH. 
Use the "export" command of the OSX shell, preferably putting it in the 
hidden file ~/.bashrc

i don't know what the hell is this.

oops. how do i fix this bug? but it worked when I coded it. Try to ignore 
it for now...

I don't recall ever seeing these.

It seems like GCC 4 and OSX 10.4 are introducing new warnings I have never 
seen, because GCC 4 is pickier on what is correct C++ and/or ObjC++.

It seems those warnings are harmless though. On the very latest GCC 4, 
I've seen "declaration does not declare anything" be an error that aborts 
compilation. I don't know what the problem is, so if it ever becomes an 
error for you, then either configure with --no-quartz, or fix my bug.

But it seems like GridFlow has compiled fine. Once you fix the problem 
with detecting Pd and do make && make install, you should be able to run 
GridFlow.
