No, I don't get these warnings, so it's something on your system that
triggers these.

For good measure I repeated this with /usr/local not existing at all and
the result stays the same.

If its just a warning then there really isn't a problem that needs
fixing, but anyway there is no presumtption that the site directories
must exist anyway. All installation methods are supposed to create
leading path components.
> Could the perl package just include these empty directories?
See above and /usr/local is off-limits for packaging.
