This likely means that some required external (C-level) library is
either missing on your system or cannot be found.

Typical approach to resolve an issue of this kind: look for installation
instructions, especially instructions telling about external dependencies.
Ensure, all dependencies are installed. In case, they are
installed in non-standard locations, use "LD_LIBRARY_PATH" to make
those installations known.
