Here is how I like to install chicken for building Megatest.

This guide assumes you have the Megatest fossil and are in the build-assist directory and
that you have the opensrc fossil with uv synced:

fossil clone https://www.kiatoa.com/fossils/megatest
fossil clone https://www.kiatoa.com/fossils/opensrc;cd opensrc;fossil uv sync

Make a build directory and go to it:

mkdir build;cd build

Make a destination directory and set PREFIX

export PREFIX=/opt/chicken/5.3.0; mkdir -p $PREFIX

Get chicken:

wget https://code.call-cc.org/releases/5.3.0/chicken-5.3.0.tar.gz

Extract, build, and install chicken:

tar xf chicken-5.3.0.tar.gz; cd chicken-5.3.0; make PLATFORM=linux PREFIX=$PREFIX install; cd ..

Install all needed eggs.
for egg in $(cat ../ck5-egg.list);do echo $egg;ck5 chicken-install $egg;done

Now run the script ../iup-compile.sh for remaining instructions

#!/bin/bash
# /opt/chicken/5.3.0
# WHICHCKVER=5.1.0_WW45
WHICHCKVER=5.3.0
