[kyrieb-ekat]

Log space for staff removal using gamera; thank you Lucas for your earlier help. Other details on progress in this can be found here hsnr-gamera/gamera-4#72 . Per last recommendation in other thread, trying recommendations, then worst case trying the Ubuntu attempt.

installation fix in the png_support.py file to add the specific libpng path worked, proceeding to trying to get the wrapper fix going.

# wrapper script for running gamera_gui
