This looks like an issue with the PGP-signature of the ARCH package. We 
cannot help here. You'll need to ask the maintainers of the package:
https://www.archlinux.org/packages/extra/x86_64/cantor/

Alternatively, since you're going to compile from the sources anyway, 
you can 'git clone' Cantor's code from the official repository and 
compile it.
However, you'll need to manually install couple of devel-packages for 
the libraries used by Cantor...

Alexander
