You left out the interesting part! Which user's profile should be  
modified, just the users that installed the package? Too bad if a  
user tries to keep admin privileges away from his normal account (or  
if a parent installs python because her kid wants to program in  
python). You could also modify /etc/profile (and /etc/csh.login  
and ...) to modify the PATH for everyone, change environment.plist  
or ...

This would also make it harder to do unattended installs of Python  
(using Remote Desktop's install feature, or even using installer(1)  
in an ssh session).

Another option is making a .mpkg for python and have one subpackage  
that does the 'echo got yes!' part in its postflight script  
(unconditionally) and add tekst to the ReadMe screen that tells the  
users to select this package if he wants to modify the shell  
environment.
