No, that's not it:

You're not passing -n before -v7. You're passing $(ECHO_N), and  
you've set $(ECHO_N) to empty on Leopard. But I don't think you should:

I don't know about this "\c" thing.

The issue is that "echo -n" on Leopard works, by design, in bash but  
not in sh. And your Makefile sets SHELL=/bin/sh. If I set $(ECHO_N)  
to "-n" and SHELL to /bin/bash the printing works correctly. Or you  
could call /bin/echo -n instead of echo -n, but I think setting SHELL  
to bash if bash is available is the proper solution. Here is the  
documentation on echo in Leopard:
