Building from source

Releases are the best way to start
Current version is 4.7.0
GCC and GNU make needed to build, nothing else
  $ wget http://code.call-cc.org/releases/4.7.0/chicken-4.7.0.tar.gz
  $ tar xfz chicken-4.7.0.tar.gz
  $ cd chicken-4.7.0
  $ make PLATFORM=linux
And as root
  # make PLATFORM=linux install
Done!
