CPANの更新で問いただされるapxsのパス
which apxsでも見つからなくて、
find / -name apxsを叩くとかなり時間がかかって
/user/sbin/apxs
と表示された

昨日、yum一括更新を行ったのですが、その後でどうもクローラが正常に機能しなくなりました。
ログを見てみると、Compress::Zlibで以下のようなエラーを吐いていることを確認。（コピペでなくて入力なのでタイポあるかも）

dualvar is only available with the XS version of  Scalar::Util at /usr/perl5/lib/site_perl/5.8.8/Compress/Zlib.pm line 9

つまりはScalar::Utilのせいで動かないらしいです。
そこでCPANからScalar::UtilをiinstallしようとしてもNOT OKになってしまうので、とりあえず

force install Scalar::Utilde

でしのぐことに。
おそるおそるクローラを起動するとエラーを吐かずに正常に機能するようになりました。
でめたしでめたし。

Perlでtwitterに何かをやらかすにはNet::Twitterというモジュールを利用するといいようです。
早速Net::Twitterを入れてみることにしました。
ちなみに、WindowsVistaはActivePerl 5.8.8です。
ppmでは用意されていないので、CPANからインストールします。
しかし、実際に実行してみると、いろいろ足らないからインストールしますよといわれて、言うとおりにインストールしたのですが、あちこちでNOT OKとなってしまいます。

==> Auto-install the 9 mandatory module(s) from CPAN? [y] 

とりあえずそのままYを押して足らないものを入れさせてみましたが、ぜんぜんだめでした。

ちなみに、CentOS5のPerl5.8.8でも同じような現象に。CPAN自体をアップデートしてやり直してもだめ。yumから1つ1つ入れてみようと思って、まず

yum install perl-Moose

を終えても、CPANからはまた入れなおそうとしてしまいます。
Mooseという新しい技術を利用するのもいいのですが、入れること自体がハードルが高いとあまり意味がないですね。別のOSで試すとか、あきらめるしかないのかなぁ。がっかり。

えらいことになった。
とりあえずTerm::ReadKeyを入れればいいらしい

[root@localhost ~]# cpan
Sorry, we have to rerun the configuration dialog for CPAN.pm due to
some missing parameters...

Normally CPAN.pm keeps config variables in memory and changes need to
be saved in a separate 'o conf commit' command to make them permanent
between sessions. If you set the 'auto_commit' option to true, changes
to a config variable are always automatically committed to disk.

 
Always commit changes to config variables to disk? [no] 

A Build.PL is run by perl in a separate process. Likewise we run
'./Build' and './Build install' in separate processes. If you have any
parameters you want to pass to the calls, please specify them here.

Typical frequently used settings:

    --install_base /home/xxx             # different installation directory

 
Parameters for the 'perl Build.PL' command? [] 

Parameters for the './Build' command? Setting might be:

    --extra_linker_flags -L/usr/foo/lib  # non-standard library location

 
Your choice: [] 

Do you want to use a different command for './Build install'? Sudo
users will probably prefer:

    su root -c ./Build
 or
    sudo ./Build
 or
    /path1/to/sudo -u admin_account ./Build

 
or some such. Your choice: [./Build] 

Parameters for the './Build install' command? Typical frequently used
setting:

    --uninst 1                           # uninstall conflicting files

 
Your choice: [] 

Please remember to call 'o conf commit' to make the config permanent!

えっと、あとはどうすればいいんだろう？

Windowの場合、CPANではNOT OKがでるけど、ppmで簡単に追加できた。

Linux（CentOS）の場合、cpanではNOT OKが大量に出て、個別にモジュールを入れていっても、開発系のライブラリがほとんど入ってないためか、それぞれがNOT OKになってしまう。
結局yumから1つづつ入れていくことになった。
perl-XML-DOM
perl-DIgest-SHA
libxml2
libxml2-devel
Sys-Syslog
perl-Log-Log4perl
んだけど、ログに関するライブラリが入らない。
よくよく見ればCPANの起動時にBundle::CPANを入れろと書いてあるではないか。そういうことならと入れてみる。
何事もなく無事に終了し、Net::Amazonも難なく入った。
結局何が問題なのかって、Bundle::CPANを入れてなかったことだけが問題だったのかもしれない。
