I want to add command-line support for PHP5 on my server. When I run aptitude install php5-cli I get a message saying that my PHP modules/packages have unmet dependencies.

Here is a list of packages that suffer from these "unmet dependencies" and needs and upgrade:

• php5-gd
• php5-curl
• php5-mysql
• php5-cgi

They all depend on php5-common.

Can I upgrade the packages just like aptitude suggests without causing any disruptions to the live site?
