Title: Use SDKROOT = macosx and MACOSX_DEPLOYMENT_TARGET

There is no 10.6 SDK in Mountain Lion; only 10.7 and 10.8 ( https://code.google.com/p/chromium/wiki/Xcode4Tips#Xcode_4.4 ), so probably it's better to use latest available sdk and set deployment target as apple suggests https://developer.apple.com/library/mac/#documentation/DeveloperTools/Conceptual/cross_development/Configuring/configuring.html
