10.5.7 is Leopard.  The readmes with the GRASS installers say 10.5  
(Leopard) and 10.4 (Tiger), so you should be able to figure it out  
(though Mac users tend to not read readmes ;)

I don't know about the compatibility of the GUI with 2.6, one of the  
GUI developers could better answer that.  But the wxpython that it  
uses has binary components that are compiled for a specific version of  
Python and may not work as expected for another version.  The wxPython  
that I bundle expects Python 2.5.x.  wx is usually in the python path  
of the python it's good for, but my bundled wx will be seen by any  
python.

Normally GRASS will use the first Python it finds in your shell PATH,  
which will now be 2.6.2.  you can override this by setting  
GRASS_PYTHON in your shell, and to make this work with the OSX app  
startup, it needs to be set in your ~/.bash_profile:

export GRASS_PYTHON=/usr/bin/python

I should add this to my binaries since they expect a 2.5 version and  
many users might have installed 2.6 or even 3.0.
