Mono installation on Linux

Using Package Management Systems for linux such as RPM, Red Carpet, Yum, Deb, Portage, Fink, DarwinPorts ...
1. RPM:

• download and unzip mono-all.zip
  
• sudo rpm -Uvh *rpm
  

2. Yum
Yum, another RPM compatible system is found in Fedora based distributions and can be used to install Mono and dependencies.

On Fedora Core 3, Putting the mono.repo (http://www.go-mono.com/download/fedora-3-i386/mono.repo) file in /etc/yum.repos.d will allow you to install mono and related packages.

3. Deb and Portage
Mono can be usually found in Debian (http://pkg-mono.alioth.debian.org/) (Debian, Ubuntu distributions) and Portage (http://www.gentoo-portage.com/dev-lang/mono) (Gentoo) systems.
These package system are not compatible with RPM based system.
