I believe you have to disable CGO_ENABLED for this, so adding CGO_ENABLED=0 before make retina-binary should work. Can you give us addition contexts i.e the reproduce steps as well as the platform you used to build?

I don't disable CGO_ENABLED manually. CGO_ENABLED=0 doesn't seem to take effect actually. I have open a pr to fix it(#129). PTAL.
