PHP5.3でPEAR/Registry.phpがエラーを吐く件

ついに我が家のサーバのPHPを5.3にアップグレードしました!
# yum remove php
# yum remove php-*
# yum install php53
# yum install php-pear
# yum install php53-*

インストールしたPEARライブラリを確認しようとすると、
# pear list

: Function eregi() is deprecated in PEAR/Registry.php on line 735 

のようなエラーが沢山出てきました。
どうやらpearがPHP5.3に対応してないみたいです。

The 'pear' command is now at your service at /usr/bin/pear

** The 'pear' command is not currently in your PATH, so you need to
** use '/usr/bin/pear' until you have added
** '/usr/bin' to your PATH environment variable.

Run it without parameters to see the available actions, try 'pear list'
to see what packages are installed, or 'pear help' for help.

Thanks for using go-pear!

で、エラーが出なくなりました。
とりあえず、大丈夫そうです!
