今日「portupgrade -a」したらなんかエラーが

** Port marked as IGNORE: security/pecl-hash:
cannot install: doesn't work with PHP version : 5 (Doesn't support PHP 5)
** Port marked as IGNORE: devel/pecl-json:
cannot install: doesn't work with PHP version : 5 (Doesn't support PHP 5)
** Listing the failed packages (-:ignored / *:skipped / !:failed)
- security/pecl-hash (marked as IGNORE)
- devel/pecl-json (marked as IGNORE)

peclってPHPの拡張ライブラリ関係ぽいけど、バージョン違いのエラー？
