Your version of gtkmm is probably too old. That method was added in
gtkmm 2.20 apparently:
http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGdk_1_1Drawable.html#9d4fb469ceab1175d9d4b788ae034d2e
though it's just possible that it really only appeared in 2.12.

What version of gtkmm do you have?
Try pkg-config gtkmm-2.4 --modversion.
