I've now managed to resolve this. Was due to multiple libgvc versions present in the system. My solution, which unfortunately isn't elegant, was to hardcode the library name into draw/__init__.py instead of using ctypes.util.find_library. The problem with find_library is that it doesn't consult LD_LIBRARY_PATH, making the search algorithm rather inflexible.

libgv = ctypes.CDLL("libgvc.so.6.0.0") # libname = ctypes.util.find_library("gvc") # if libname is None: # raise OSError() # libgv = ctypes.CDLL(libname)

Best, Mikhail

There should be a way to fix this in a more robust fashion... Could you perhaps open a ticket, so that I don't forget?
