+Subject: Fix CPAN::FirstTime defaults with nonexisting site dirs if a parent
+ is writable
+
+The site directories do not exist on a typical Debian system.  The build
+systems will create them when necessary, so there's no need for a prompt
+suggesting local::lib if the first existing parent directory is writable.
+
+Also, writability of the core directories is not interesting as we
+explicitly tell CPAN not to touch those with INSTALLDIRS=site.
+
