To get a bit more back on topic, For anyone still interested in running code lobster in linux. Even though these aren't as good as a native version, they are good work around's for this problem.
For Linux you can use something called 'wine' to run windows programs, i've had a pretty hit and miss experience with wine, but it's worth a try.
Another alternative, which is the easiest, and most reliable, check out virtual box, it lets you run an alternate OS in a Virtual Machine. It's free too. To run code lobster you just need to create a windows XP machine, set it up, install the guest additions, and install code lobster. It will run fine, and you can do this in ubuntu, linux, mac etc...
There are loads of tutorials online on how to do the above things, google is your friend.
