thanks for the quick reply.

i tried ./configure --no-opengl
upon make distclean but that lead to the same result for
gridflow.pd_linux: undefined symbol: cvEllipse

as this seems an openCv object, which is included directly by
gridflow (not via Gem) from src/opencv.cxx
i checked the config.log for opencv and really there was a line saying:
"Package opencv was not found in the pkg-config search path"

installing libopencv-dev fixed that and it's all good now :)

thanks+cheers,
