v0.3 Previously tried to load libuuid.so which is usually a symbolic
link to libuuid.so.1, but is often not installed by default.
Changed to explicitly load libuuid.so.1
https://docs.perl6.org/language/nativecall#ABI/API_version
v0.4 Use NativeLibs to try various libuuid.so.* versions.
v0.5 use NativeLibs:auth; to make sure it doesn't use
the DBIish version.
