Apparently you need to use "nm --dynamic" instead of just "nm", although I didn't need it on my system (but I'm using arch and not debian/ubuntu like you). (based on https://lists.debian.org/debian-user/1997/11/msg00428.html)
I'm not even sure if there is anything interesting to find in these so files or not. I'm just guessing random stuff because I don't understand why it can complain about just one missing symbol.
Edit: running "nm --dynamic /usr/local/lib/libsfml-graphics.so -C | grep sf::Image::~Image" might be more clear and should return 2 lines.
