I don't know what kind of development you're doing, but it would be less of a kludge to install MacPorts as it can really save one a lot of work installing dependencies.

However, that nor your kludge would have allowed you to find the glitch in Digia's package - in the QtCore library I have installed through that same installer (dated Jan. 5th of this year) that same library is referenced ...

The proper way to repair this is

%> install_name_tool -change /opt/local/lib/libz.1.dylib /usr/lib/libz.1.dylib  /Users/Shared/Toolkits/Qt-5.4.0/5.4/clang_64/lib/QtCore.framework/QtCore

That way you can use whatever bundling methods you use to bundle the Qt libraries with your products.

The output from otool already showed that, before my answer!
