I had the same message.
Although I already had XCode 6.0.1 from the Mac App Store, from which I
had already chosen to install CLI tools, I tried "xcode-select
--install" anyway, as MacPorts suggested to me.

It triggered some OS X software install window, and then it started
compiling fine, without error message so far. I don't know about cmake.
It is currently compiling atlas...
