手っ取り早く言うならば、Cent5.3の標準Perlですね。0.19をテスト
まずは、現時点で最新バージョンである0.19から。# cpanm Cache::Memcached::Fast Fetching http://search.cpan.org/CPAN/authors/id/K/KR/KROKI/Cache-Memcached-Fast-0.19.tar.gz ... OK Configuring Cache-Memcached-Fast-0.19 ...

0.18ならどうだ
こちらも試します。# cpanm K/KR/KROKI/Cache-Memcached-Fast-0.18.tar.gz Fetching http://search.cpan.org/CPAN/authors/id/K/KR/KROKI/Cache-Memcached-Fast-0.18.tar.gz ...

Installing K/KR/KROKI/Cache-Memcached-Fast-0.18.tar.gz failed. See /root/.cpanm/build.log for details.やはりダメ。build.logの中身はこんな感じ。

See /root/.cpanm/build.log for details.一部違わず同じ箇所でこけてますねえ。
0.17なら無事入りました
0.17も試して見たところ、こちらは無事にインストール出来ました。問題のmagic.tとは？
しかし、magic.tのテスト内容が気になる所。とりあえず問題の箇所をクローズアップしてみます。package MyScalar;
use base 'Tie::StdScalar';
sub FETCH {
"Другой.ключ"
}
package main;
tie my $scalar2, 'MyScalar';
ok($memd->set($scalar2, $scalar2));
ok(exists $memd->get_multi($scalar2)->{$scalar2});
SKIP: {
eval { require Readonly };
skip "Skipping Readonly tests because the module is not present", 3
if $@;
# 'require Readonly' as above can be used to test if the module is
どうやら、tie関連のテストのようです。0.18以降でこのテストが追加されているのを見ると、おそらくChangesにも何かしら記載があるはずです。
では、Changesを見てみます。
0.18 2010-04-06
- make module thread-safe, and fix several bugs. No need to
upgrade unless you experienced limitations mentioned below.
Changes since 0.17:
Fix RT#56142: handle Perl magic. Tied scalars, arrays and
hashes are supported now, as well as Readonly variables and
other magic stuff.
Fix t/command.t failure on some Solaris distributions.
Make module thread-safe with Perl >= 5.7.2.
僕のグダグダ英語スキルによると、以下のように理解できます。「Perl magicに対応。tieされたスカラや配列、ハッシュは、従来どおり、読み取り専用変数やその他のmagic同様にサポートされるようになった。」
どうやらこれは、RT上でチケットが発行されていた問題らしく、こちらでそのやりとりを確認できます。
今回の問題もRTで既にチケット発行済だった
そして今回の問題も、RT#57150としてチケットが発行されており、既にステータスが「着手」となっておりました。さすが。おそらく、次期リリースのタイミングでこの問題は解消することでしょう。それまでは、特段差し支え無ければ0.17を使うなり、0.19をforceインストールしたりして凌ぐことになります。
2010-9-22 追記
現在進行形で現象が発生しています。
