Download full freeware version for GNU/Linux:http://rapidshare.de/files/21293529/IceLand-1.2-linux.tar.html
I have no good webspace for it, probably that link will be dead after 30 days.
To install - you need a bunch of libraries and tools (see readme).
To run - if you have your Crystal Space installation then unset $CRYSTAL or rename your CS directory.
Deploying for Gnu/Linux is hard, may not work on some distros.
