My linux skills are "questionable' but I'd thought something like that
would have already been properly configured when gcc gets pulled down
and installed with a package manager.  But I'm learning...

My ld.so.conf file references all '*.conf' in /etc/ld.so.conf.d/. And
/usr/local/lib is present in one of them.

In order to get libguestfs-test-tool to work I made this link:
   sudo ln -s /usr/local/lib/libguestfs.so
/lib/x86_64-linux-gnu/libguestfs.so.0

If there is a more correct solution please let me know.
