reported by C<%Config::Config> under the keys C<dynamic_ext>,
C<known_extensions>, C<nonxs_ext> and C<static_ext> have not changed, and
still use C</>. Hence this change will not have any affect once perl is
-installed. However, C<Attributes::Handlers>, C<Safe> and C<mro> have now
+installed. However, C<Attribute::Handlers>, C<Safe> and C<mro> have now
become extensions in their own right, so if you run F<Configure> with
options to specify an exact list of extensions to build, you will need to
change it to account for this.
