packages specified by install.sh

I plan to use SuSE Linux Enterprise Server 10 as my hosting server OS, virtualmin to manage websites & supporting services, and Joomla to create the site content.

I'd like to know what package versions the install.sh script downloads & installs. SLES 10 already has the following packages. Can I just install the rpm & go from there? I'm sure I'll have to specify the paths for each of the packages listed below.

package - version

apache2 - 2.2.3-16.2 PHP - 5.1.2-29.25.3 MySQL - 5.0.18-20.8 IMAP (Cyrus) - 2.2.12.27.6 ... Should I be opting for Dovecot here?

Thanks!
