I'm not sure why the xz port didn't get installed before the llvm-3.5 port, since the xz port is listed as an extract dependency of the llvm-3.5 port.

Does manually installing the xz port first work around the problem?

sudo port install xz

I note this was not a clean build attempt. You should always ​clean and try again before reporting a problem.

I also note the error message that xcodebuild failed and Xcode was not installed. You must install Xcode and the Xcode command line tools to use MacPorts. Consult our installation instructions if you need further assistance with that.

I think this is a duplicate of #34547.
