Fixed in http://bitbucket.org/segv/hg-website/changeset/b7d326bc57f9

Just ran into this problem as well.  I'm running 10.5.8, and clicking on the 
big "Download" button at http://mercurial.selenic.com/ sent me to

http://mercurial.berkwood.com/binaries/Mercurial-1.5.1-py2.6-macosx10.6.zip

Greg;

I went to "mercurial.selenic.com"

This problem is still reproduceable this morning.

whenever I try to log in there.

Precisely which URL did you hit?

I presented the following User Agent:

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2)
Gecko/20100115 Firefox/3.6

and got

mercurial-1.5+20100307-py2.6-macosx10.6.mpkg

when I clicked on the big cyan "Download now" arrow icon.

Naturally, it couldnt install because I lack "Apple Python 2.6" - which must
come with Snow Leopard, I guess.
