It turned out that it is quite painless to make Debian packages for
Chicken 2.41 based on the 2.3 build scripts. If anyone is interested,
I have built Chicken packages for Debian stable and placed them at the
following repository:
deb http://www.neuro.gatech.edu/mrci/debian stable main
deb-src http://www.neuro.gatech.edu/mrci/debian stable main
In order to get those packages, add the above lines to
/etc/apt/sources.list and do `apt-get update; apt-get upgrade`. I have
also uploaded the source package, which is simply the Chicken 2.41
tarball with the debian/ subdirectory from the Debian chicken-2.3
package.
