Installation Guide Update
Please follow the installation instructions at http://www.davical.org/installation.php which should be the most current official installation instructions.
If you find problems with that document, please do not write an update in the wiki, but tell us about it on one of the Mailing Lists, or via the DAViCal IRC Channel. By all means do collect your thoughts together in a private document beforehand though.
You may also want to review other people's Installation Experiences in specific distributions / versions, or visit the Installation Stuff page where there are some other links to distribution specific pages.
