Magma Seaside package?

Exploring how Seaside and Magma could work together, I am trying to install Magma in a 3.9 image. According to http://wiki.squeak.org/squeak/5817 the 'Magma seaside' package is needed. I cannot find it...

In the SqueakMap browser I see Magma server, client and tester. But no Magma seaside. I did find the MagmaServerLoader through Montecillo.

I guess that the following code is a little bit out of date (from the Pier install script): magma := squeaksource project: 'MagmaTester'. magma install: 'MagmaServerLoader'; install: 'Magma server'; install: 'Magma client'; install: 'Magma seaside'; install: 'Magma sunit'.

How can I try Seaside+Magma in a 3.9 image?

Thank, Thierry
