Hi Frank, thanks for the information. If you always use /usr/local/lib then what do you do when you need to run two different independent applications which have different requirements?

However, when I attempt to load libgdk-x11-2.0.0.dylib it complains
that it cannot find a particular symbol in /usr/local/lib/libcairo.dylib. Why is it complaining about /usr/local/lib/libcairo.dylib?
Most of those dylibs are symlinks and libgdk may depend on a name which exists in /usr/local/lib but not /usr/local/Cellar, maybe? ldd can tell you what a given dylib depends on.
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.
Best, Frank
