OpenCV 3.1.0: /usr/local/include/opencv2/legacy/legacy.hpp can't compile

I'm getting loads of errors like 

/usr/local/include/opencv2/legacy/legacy.hpp:2994:12: error: 'CvSubdiv2DEdge' does not name a type
/usr/local/include/opencv2/legacy/legacy.hpp:3002:12: error: 'CvSubdiv2DPoint' does not name a type
/usr/local/include/opencv2/legacy/legacy.hpp:1757:36: error: 'cv::EM' has not been declared

With OpenCV 2.4.13 it compiles just fine. It looks like they actually forgot to add some necessary includes into legacy.hpp. What's going on?

Sorry for being misleading, but there's actually NO such header in the standard setup. My setup was mixed up with another, older version of opencv, and it wasn't packed into a deb file, just a bunch of files within /usr/local/. Funny thing is, it was a clean install.

After reinstalling the OpenCV from scratch and removing those old files, errors changed to legacy.hpp being missing - which is exactly what is required here.

Here is the proof: http://answers.opencv.org/question/42622/opencv-30-deprecated-opencv_legacy-module/. Also, from OpenCV Transition Guide: "legacy, nonfree modules have been removed. Some algorithms have been moved to different locations and some have been completely rewritten or removed."
