/System/Library/Frameworks is the location for Apple-supplied system 
Pythons.  OS X 10.6 ships with complete versions of Python 2.6 and 2.5 
(and the shared libs for 2.3).  So you won't find a 2.7 folder there in 
10.6.8.  In OS X 10.7 and 10.8, Apple ships 2.7, 2.6, and 2.5.

If you used one of the python.org installers to install 2.7, it will be 
installed into /Library/Frameworks and, by default, symlinks will be 
installed in /usr/local/bin for python, python2.7, etc.  Since 
/usr/local/bin/kivy appears to be a script of some sort, examine it and 
see exactly what command is on line 24.  The solution might be as simple 
as editing a line there to remove the "/System" part.

I'm not sure what you are proposing there.  But you should never attempt 
to install anything into /System/Library: that's part of OS X and 
controlled by Apple.
