While this technique is useful, it is not producing results for me.
I can see that simply installing all libraries resolves the dependency.
Perhaps the package maintainer could try building the package on a
system with just the default libraries installed? This should produce a
clear error from the linker as to precisely which library is in question
vs. the run-time that simply gives up.
