我使用本教程升级到 PHP5.3：http://www.debiantutorials.com/how-to-install-upgrade-to-php-5-3-on-debian-lenny/
它删除了以下软件包：
Removing php-pear ...
Removing php5-pgsql ...
Removing php5-mysql ...
Removing php5-mcrypt ...
Removing php5-ldap ...
Removing php5-gd ...
Removing php5-curl ...
Removing php5-sasl ...
Removing php5-cli ...
一切看起来都很好，它警告我这些软件包将被删除，这很好，我想我可以在之后安装它们。但现在，当我尝试时，它警告我缺少依赖项：
The following packages have unmet dependencies:
php5-cli: Depends: libc6 (>= 2.11) but 2.7-18lenny7 is to be installed
Depends: libdb4.8 but it is not installable

E: Broken packages
我该如何解决此问题并取回这些内容？
