Within the past years, I slide from one CURRENT to the next. There was no accdent as far
as I can recall, but due to the fact I do quite often a recompilation of the system, the
likelyhood of hitting the fan (or problems) is quite high. I gues this is a remnant of
some problems not visible to me.
I blew the /usr/include/include folder, but then the system rejected to buildworld. I had
to reinstall world, did a complete buildworld/buildkernel with recent sources and started
recompilation of updated ports. Now, graphics/opencv2-core compiles!
Thank you very much. Quite impressive!

Content of /usr/local/libdata/pkgconfig/eigen3.pc:

Thank you very much and kind regards,
