StatusNet comes bundled with a number of libraries required for the application to work. However, it is best that you use PEAR or you distribution to manage - libraries instead, as they tend to provide security updates faster, and may offer improved performance.

-

On Debian based distributions, such as Ubuntu, use a package manager (such as "aptitude", "apt-get", and "synaptic") to install the package listed.

-

On RPM based distributions, such as Red Hat, Fedora, CentOS, Scientific Linux, Yellow Dog Linux and Oracle Enterprise Linux, use a package manager (such as "yum", "apt-rpm", and "up2date") to install the package listed.

-

On servers without a package manager (such as Windows), or if the library is not packaged for your distribution, you can use PHP's PEAR to install the library. Simply run "pear install <name>".
