Zimbra Desktop 64bit Requires ia32-libs on Fedora

I'm reposting this information buried in a post from Tuan of the Zimbra Desktop forums, to hopefully make it easier for me to get Zimbra Desktop working again after a fresh install. 

I have reported this issue directly to Zimbra, but they have not fixed the issue when I originally wrote this entry.

UPDATE 3rd April 2012: A Zimbra employee suggested it may only be the glibc.i686 package that is required to meet the "ia32-libs" issue.

UPDATE 19th April 2012: Blogger "displacedgeek" confirmed that xulrunner.i686 is the only thing that seems to resolve this issue on openSUSE Tumbleweed.

Problem

When you run the Linux Zimbra Desktop install.pl file, a missing package dependency message is echoed back to you by the script.

Steps to Reproduce

1. Download the Zimbra Desktop installer tar.gz.
2. Extract the folder to you Downloads directory.
3. In terminal, cd to the extracted directory.
4. Run install.pl
5. Note the output in the script.

Actual Behavior

While installing, you see the following error message:

WARNING: ia32-libs is missing for x86_64 platform. This package is required to run Zimbra Desktop on 64-bit Linux.

There are no "ia32-libs" packages in the fedora repos. This error message is outdated.

Workaround

Install xulrunner 32-bit packages. There is a package in the dependencies for this package that contains the required "ia32-libs" libraries.

Run the following command:

sudo yum install xulrunner.i686

Attempt to run Zimbra Desktop, and the program will start.
