-#Darwin (macos) builds:

-To build with the x86_64-apple-darwin11 you require the mac os developer tools in MacOSX11.1.sdk.
-Download it from apple, or search for it on github. Create a new directoty called SDKs in this
-directory and place the entire MacOSX11.1.sdk folder in it. The depends build will then pick it up automatically
-(without requiring SDK_PATH).
