Han, Michael,
I've got the exact same scenario on my El Capitan. With the help of
Michael's pointers, I managed to track down what goes wrong.
Michael pointed out there is a call to some function that will return an
empty string for systems where xcodebuild barfs, and the later code
checks if the variable is set. Obviously it is (to an empty string),
with a result of "-isysroot".
I've patched the function to return / in case xcodebuild returns nothing
useful, such that we fall back to /usr/include, which makes the whole
thing compile for me.
Fabian
