This is already an extra-very-long-term solution, as it's almost
30 years old. It's how Unix deals with shared objects.

Instead of setting LD_LIBRARY_PATH you may want to add mono's lib
dir to /etc/ld.so.conf or /etc/ld.so.conf.d/mono or wherever
your system is configuring LD paths.

Alternatively, follow these docs:
