Hmm, you're right -- it's a mistake in the install guide. We actually
don't have any binaries to install yet. So far we only have small
example application scripts in the apps/ folder.

I'll update the installation guide, thanks for the report! :-)

Yes, you need to install GMPY:

  http://code.google.com/p/gmpy/

(or use a package, if you one is available in your package manager).
