Не мог определить местоположение пакета libpango1-dev

Я использую Ubuntu 14.04, OpenCV 3.0.0, это - список команд и ошибок попробовать мою opencv библиотеку, будучи установленным

    linaro@linaro-nano:~/opencv/samples/cpp$ ./cpp-example-facedetect lena.jpg

    This program demonstrates the cascade recognizer. Now you can use Haar or LBP features.
    This classifier can recognize many kinds of rigid objects, once the appropriate classifier is trained.
    It's most known use is for faces.
    Usage:
    ./facedetect [--cascade=<cascade_path> this is the primary trained classifier such as frontal face]
       [--nested-cascade[=nested_cascade_path this an optional secondary classifier such as eyes]]
       [--scale=<image scale greater or equal to 1, try 1.3 for example>]
       [--try-flip]
       [filename|camera_index]

    see facedetect.cmd for one call:
    ./facedetect --cascade="../../data/haarcascades/haarcascade_frontalface_alt.xml" --nested-cascade="../../data/haarcascades/haarcascade_eye.xml" --scale=1.3

    During execution:
        Hit any key to quit.

У меня был libgtk2.0-dev, отказавший, чтобы быть установленным с начала, но я думал, что вызываю его со способностью вместо Кв. - добираются
