 You need Xcode with Command Line Tools in order to compile and build the package. Xcode usually supports two adjacent SDKs (e.g. 10.9 and 10.10). You need to obtain an older Xcode package to achieve older SDKs. Store the SDKs into the directory `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs`.
