Hello,

I realize this thread is older, but it is also incomplete. How do you install it on other OS's, such as Linux or Mac OS X? The writer did not specify an operating system, and we need to be careful that we include complete descriptions for all mainstream OS's out there.

The easiest way in most Linux/BSD distros is to use the default package manager, this way you are likely to install the version that is recommended and tested for your distro version and install the components in their default locations.
