Note: This version of the VDT (1.10.1) is supported, but is not our latest stable release. The current stable release is 2.0.0.

Installing Pacman

The VDT is distributed using Pacman. Pacman is a package manager like RPM or dpkg, but is much more powerful and designed to work on multiple platforms. Unfortunatly, Pacman does not come standard on any operating systems so you need to download and install it yourself.

Download Pacman. We currently recommend version 3.26. You must use version 3.20 or later. Earlier versions will not work.

Unpack the tarball:
```
> tar zxvf pacman-3.26.tar.gz
```
Setup your environment to use pacman. This example assumes you're using the Bourne shell or Bash. If you're using the C shell you should source setup.csh instead.
```
> cd pacman-3.26
> source setup.sh
```

Please note: As of Pacman 3.25, the default output for Pacman is now "brief": progress messages overlay each other on the screen so that you can see the essential information without all the Pacman messages that you might find confusing or irrelevant. You can make this look like the old-style Pacman output instead. First, change into the directory where you will install the VDT. Then run:

pacman -v cache -v download -v tar

That's it! You can now move on and select the VDT packages you want to install.
