When executing gem install jekyll on OSX 10.8 with the standalone Command Line Tools package from Apple\'s Developer site installed (no Xcode), i run into the follo
gem install jekyll
I was having trouble with brew install hg. It was choking on the output of xcodebuild -version.
It is a horrible hack, but I replaced /usr/bin/xcodebuild with a shell script that just echoed "4.3" and was able to install mecurial successfully.
