Log Message:
Updating package for Perl5 module namespace::clean from CPAN in
devel/p5-namespace-clean from 0.21 to 0.23.

pkgsrc changes:
- adjust dependencies

Upstream changes:
    [0.23]
        - Rely on B::Hooks::EndOfScope version 0.10 to fix issues with
          new Module::Runtime versions (>= 0.012) on perl 5.10 due
          to incorrect hook firing due to %^H localisation.
        - Fix failures on 5.13.6 due to incorrect version number threshold
          (RT#74683)

    [0.22] (official fix of all the %^H ickyness)
        - Simplify the >= 5.10 PP variant even more - move the hook from
          DESTROY into DELETE
        - Force explicit callback invocation order on 5.8 PP

    [0.21_02]
        - Replace the %^H tie approach with fieldhashes, fixes all known
          corner cases and caveats on supported perls >= 5.8.1 (FC)
        - Compile away the debugger fixup on perls >= 5.15.5 (FC)

    [0.21_01]
        - More robust handling of the tied %^H in pure perl mode (RT#73402)
        - Limit the debugger workarounds to perls between 5.8.8 and 5.14,
          extend debugger support to all perl versions (FC) (RT#69862)
        - If possible, automatically install (but not load) the debugger
          workaround libraries on perls between 5.8.8 and 5.14 (RT#72368)
        - Add back dropped NAME section (RT#70259)
