[Pharo-project] How to run cog on Linux

Hi! I'm absolutely newbie on linux, so I need help. Trying to run cog on Ubuntu 11.04. I've downloaded coglinux.tgz<http://www.mirandabanda.org/files/Cog/VM/VM.r2468/coglinux.tgz>from http://www.mirandabanda.org/files/Cog/VM/VM.r2468/, unpacked it and tried to run squeak from there in various variants. For example this way: ~/coglinux/bin/squeak … In all cases I get error: "exec: 10: /home/chaetal/coglinux/bin/../lib/squeak/4.0-2489/squeak: not found" What am I doing wrong and what is the correct way to make Pharo run on Cog under linux? TIA! -- Dennis Schetinin
