ffi_lib searches in the standard locations that dlopen() would look
for the library - usually /usr/lib.  For everything else, you need to
specify by absolute path.

You can specify both "search the default paths" and "use this specific
path" like so:

module FooLib
  ffi_lib [ "foo", "/usr/local/libfoo.so", "/opt/local/libfoo.dylib" ]
end

That will try to load each of the members of the array in turn, and
stop once it has loaded once successfully.

Presumably FFI would find a library installed here, but I'm hoping it will also find a library stored at the traditional /usr/local/lib location. Will it? Any way to give it a hint (aside from providing an absolute path)?
