Ok, got it working now!
Just to let you and other ppl know, I needed two adjustments:
1) add #include "imglabels.h" to main-ocr-pageseg-xycut.cc
2) make sure /usr/local/include/ocropus/ocr-pageseg-xycut.h
and the local copy of the same .h won't collide. for example,
by copying the main...cc to a empty subdir and go compiling there.
