As Jim is on macOS there is no ldd. The command to use is

otool -L /usr/local/lib//libcairo.dylib

Seeing that Jim uses homebrew to install Cairo it is worth mentioning that brew 
install … also generates (normally) an entry in /usr/local/lib . That is why I 
always stick to using /usr/local/lib/libxyz.dylib paths when I want to ensure a 
particular library to be loaded.
