I suspect it detected you had a newer version 2.5.1 already
installed (note: that non-Apple python goes in
/Library/Frameworks/Python.framework/...) and did not want
to over-install an older version.

See above (Check /Library/Frameworks/Python... and possibly
/usr/local/bin )

  I have a DMG for 2.5.1 that I built (and am using) but I
notice there are some changes that Richard committed last week...
I will build one today and send a pointer to you and Richard
(to both the earlier 2.5.1. and today's)
since I don't have a lot of time to test it... and you can let
us know if it works for you.  If so Richard can update the DMG
on the website.

Alternatively: I'm not sure how to make it think Python2.5.1 is "not  
if you have cleared all of the files it installed in /Library/ 
...there may be some sort of package directory somewhere...
