I use Chicken every once in a while, particularly when fooling around with web stuff. They have some kick ass extensions : basic HTTP, more featurefull web server, XML query and generation. I first ran across it looking at some modal web programming samples and have continued to like it ever since. However I just ‘apt-get chicken’ installed the environment on my Ubuntu system only to find that the build was very very much out of date. Most of the extensions I installed failed to load into the interpreter cause names have changed or the extensions use new features. So I downloaded Chicken 2.2 source and installed from that in about 15 seconds. Just figured I would post in case anyone run across problems with Chicken on Ubuntu when trying to just use chicken-setup to install eggs. If you’re pointed at the same repositories I am you probably got a 1.6 build from 2004, that’s the problem.
