Please provide any additional information below.

I hope there will be no issue when Mac OS X 10.7 fully releases. Just would like to try
and highlight early on. Seems upgrades from 10.6 to 10.7 DP4 resets environment
variables. Python 2.5 becomes default, and Xcode env are gone. Have to download binary
mercurial build for OS X 10.5 and Python2.5 (http://mercurial.berkwood.com/) and
reinstall Xcode 3.2.2 from Installer DVD. After that, hg works. ./all.bash works, except
error above.
