The equinox download page was broken for a little bit. Not sure when you checked last. http://download.eclipse.org/equinox/ should show 3.8 builds. The next Equinox version (included in the eclipse SDK platform 4.2) is from the Equinox version 3.8 builds. We are currently heading into release candidates for the Juno release which will include Equinox 3.8.
