Easy Install compares the version of each component of the Citadel system on your computer to the latest version available on the download site, and only upgrades components when newer versions are available. Therefore you may run an Easy Install operation at any time to get the latest upgrades, and if no upgrades are available, it will have no effect.
If for some reason you feel that you want to force it to download and reinstall everything, simply delete the following files:
/usr/local/ctdlsupport/etc/*.sum /usr/local/citadel/*.sum /usr/local/webcit/*.sum
Then run Easy Install again, and all components will be built.
