The last part is incorrect. See e.g. http://qin.laya.com/tech_coding_help/dylib_linking.html
for more information. You need at least two versions of your
library, or tell developers that want to include the library in their
program to adapt the library's path with install_name_tool and compile/
link against this modified version because otherwise their application
will still insist on only looking for the /usr/local/lib version
(which is why distributing a /usr/local/lib version is such a bad
idea, because developers won't notice on their own machine if they
make a mistake since that version can be used without them realising it)
