Why does OS X installer require MacPython?

[Jens Alfke]

The prepackaged installers for Mac OS X at <http://mercurial.berkwood.com/ 
 > are useful, but they require you to first install the MacPython  
package. This seems unnecessary, since OS X already comes with Python  
installed (version 2.4, as of OS X 10.4; soon to be 2.5 when OS X 10.5  
"Leopard" ships.)

(Personally, I don't want to have two different installations of  
Python on my machine. I've done so in the past, but it leads to  
confusion. So I was unable to take advantage of easy Mercurial  
installation and had to build it myself.)

Could the Mercurial packages be changed to install into the right  
locations for use with the built-in Python? Or could this at least be  
offered as an option?
