Getting them installed in Ubuntu is a breeze, thanks to a script I found.
To install the Vista ClearType fonts in Ubuntu, you need to install cabextract first. Cabextract is a utility found in the universe repository, so before you run the following command, make sure you have universe enabled in your repository list. Once this is done, install cabextract using:
$sudo apt-get install cabextract

Then, once that is done, use this script to install the Vista fonts. Create a file called “vista-fonts-installer.sh” in your home (~) directory.
Then open up a text editor and copy and paste the script into that file.
Do a chmod a+x ~/vista-fonts-installer.sh to make the file/script executable.
Then run the script using:
$ ~/vista-fonts-installer.sh

The script downloads the Powerpoint Viewer installer from microsoft.com, and then extracts the Vista cleartype fonts using cabextract. These fonts are then installed in the ~/.fonts directory.

Please remember that the ClearType Vista fonts are not free as in they are not GPL-ed or made available under a re-distributable license. Since you are downloading the fonts from the MS website, and since you might already have a Windows XP/Vista license, this is not a crime, but consider yourself warned against the perils of supporting closed systems

Update::

   1. Looks like the use of these fonts are restricted to only Microsoft Windows/Vista operating systems according to the terms of the license. I am sorry, but you’ll be installing them at your own risk.
   2. Also, please make sure you use the bash shell, or change the first line of the code to #!/bin/bash
   3. In retrospect, this was a bad post – I think we’re better off not using stuff folks don’t want us to use – let’s use the better, freer, easier to install fonts.
