Well, I would have sworn ... but no. Installing fixed the problem.
"Sworn" what? It's like that for a very, very long time. The .so symlink
is an unversioned build-time file. Hence it's stored in the zlib-devel
subpackage that is needed only when building/developing something based on
zlib. And whereas it can make sense to dlopen that .so at runtime, code that
does that would need to make sure it can handle any API/ABI of the library
the symlink may point at.
