I understand that it’s a place to store a “Search path for dynamically loaded modules,” but I would be grateful if someone could please provide an example use case for $DLN_LIBRARY_PATH with Ruby.

Since Ruby cannot be linked against user C extensions in advance, it loads them at runtime as shared libraries. These extensions have to be loaded from somewhere, and that’s exactly what
DLN_LIBRARY_PATHspecifies: the list of directories where shared objects or DLLs may be found.It is similar to the
LD_LIBRARY_PATHenvironment variable, which provides the same information for the dynamic linker on Unix-like systems.
