opencv2 import problem with python

[Zenny]

Thanks John:

I am getting the following:

"% grep ZTIN2cv15FeatureDetectorE /usr/local/lib/*
Binary file /usr/local/lib/libopencv_contrib.so matches
Binary file /usr/local/lib/libopencv_contrib.so.2 matches
Binary file /usr/local/lib/libopencv_contrib.so.2.4.7 matches
Binary file /usr/local/lib/libopencv_features2d.so matches
Binary file /usr/local/lib/libopencv_features2d.so.2 matches
Binary file /usr/local/lib/libopencv_features2d.so.2.4.7 matches
Binary file /usr/local/lib/libopencv_legacy.so matches
Binary file /usr/local/lib/libopencv_legacy.so.2 matches
Binary file /usr/local/lib/libopencv_legacy.so.2.4.7 matches
Binary file /usr/local/lib/libopencv_stitching.so matches
Binary file /usr/local/lib/libopencv_stitching.so.2 matches
Binary file /usr/local/lib/libopencv_stitching.so.2.4.7 matches

I am CCing this mail to jhale for his attention, who is reportedly the
maintainer accoring to the ports Makefile.
