What causes the 'error while loading shared libraries: libncurses.so.5' error on Arch Linux?

This error typically occurs when a program requires a specific version of the ncurses library (libncurses.so.5) that is not installed or is not found in the system's library path. Arch Linux often uses newer versions of libraries, and older software might be compiled against the older version 5. The issue arises from a dependency mismatch.
