ofxBullet linking errors on compile in M

I've installed ofxBullet as described on the addons website and am having some linking errors. I am running of9.0 in XCode on OSX 10.11.1

Upon trying to compile SimpleExample:
clang: warning: -lpthread: 'linker' input unused
clang: error: invalid deployment target for -stdlib=libc++ (requires OS X 10.7 or later)

Upon moving EmptyExample to addons folder and compiling:
clang: error: no such file or directory: '/Users/collinschupman/Downloads/of_v0.9.0_osx_release/apps/myApps/src/shapes/ofxBulletEllipsoid.cpp'
clang: warning: -lpthread: 'linker' input unused

Anybody know what's going on?
