This is, fnially, the linux version of the demo. You'll have to add all symbolic links et .so files to a directory that Linux can scan to open them. If you want to install your own version of library, or it simply doesn't work, you need the version 2 of SFML and you need libjpeg-62 (often available with your package manager of your ditribution). You need libGlew 1.8 too. IMPORTANT : Please download the patch in the download section of the game !
