OpenCV 3.1 build from source - core test fails for 3 tests

Hi! I've just finished compiling OpenCV 3.1 on my 64bit Debian Jessie with a lot of features enabled (Qt, OpenGL, Matlab (I have R2014), Python2 and 3, Tesseract, Ceres etc.). Now I've started running the test. Sadly the first test fails (I haven't continued with the rest since I'd like to resolved the issues one by one). The failed tests in `opencv_test_core` are: - `Core_globbing.accuracy` - I've read somewhere that this fails do to a missing input image. Is that correct? - `hal_intrin.float32x4` - in `cmake-gui` I get `OpenCV_HAL_DIR-NOTFOUND` along with empty `OPENCV_HAL_HEADERS` and `OPENCV_HAL_LIBS`. So my guess would be that this is the reason. I have no idea how to enable HAL support though. Any pointers how to do that? - `hal_intrin.float64x2` - same as with `hal_intrin.float32x4` Just a side-note which concerns `Caffe` - has anyone managed to build OpenCV 3.1 with `Caffe` support? I tried to build `Caffe` but it fails for both Python 2.7 and 3.4 (the version I'm having) because of `python-dateutils` being 2.5 (or something similar) and the requirement being a version >=1.4 and <2. Am I supposed to handle even such low level dependencies?!?
