-r is not the equivalent of -a; -r applies only to directory; in this case 
it's completely useless; in the case of GridFlow, -a isn't even so useful; 
maybe that I should have used ln -s instead anyway. In GridFlow 0.8.5 (CVS 
only), -a is gone.

You should not copy that directory. Instead, use ln -s to create an alias, 
or add a -path line to "~/.pdrc".

On Linux, this would be because you didn't load Gem before gridflow, so 
you'd have to do this:

   -lib Gem -lib gridflow

But I remember that with Koray I tried to do it and it didn't work, and we 
traced it back to the "private mode" that Pd uses in loading .pd_darwin 
files, which prevents GridFlow from accessing anything in GEM.

To fix that problem, you have to modify the Pd source code, or switch to 
Linux, or use a version of Pd that doesn't have that problem (if there's 
one).
