I've downloaded the installation package of scilab 4.0 from the official site scilab-4.0.bin.linux-i686.tar.gz. When I've decompressed the file and when I've gone to the directory .../scilab-4.0 I should digit only 'make' (as suggested in the website and in the readme file), but the result in the terminal display is 'command not found'. If I digit './configure' the result is 'Hmm... this is a binary version'. How I can install it ? (I've Ubuntu Dapper Drake 6.06 and consider that I've no internet connection on ubuntu for a driver problem).
