I was attempting to follow the guide here:
http://www.equinox-project.org/wiki/installingonarchlinux?rev=1370080384
However the current wiki revision appears broken, and when I follow the instructions on the previous revision it fails with:
error: edelib: missing required signature
:: File /var/cache/pacman/pkg/edelib-2.0.1-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n] n
error: ede-common: missing required signature

There should be a signed keyring for these packages. It is possible to override this with:
Siglevel = Never

If someone could throw a keyring on this repo it would be most helpful, as well as more secure.

Thanks.
