(*) For Linux 64-bit distros, you need to install 32-bit supporting libraries. So, for Debian-based distros, install them using:
sudo apt-get install ia32-libs libc6-i386 libcurl3If you are using a Debian 7+ or Ubuntu 13.10+ version, you should use the multiarch way:
dpkg --add-architecture i386 apt-get update apt-get install libc6:i386 libcurl3:i386For Fedora/Redhat/Centos distros:
sudo yum install glibc.i686 sudo yum install libcurl.i686For FreeBSD, no prebuilt binaries yet, you need to cross-compile, or get the Red sources, a Rebol interpreter (here) and a couple packages: libcrypto.so.8, which can be found in the openssl package, and libcurl.so.4 (temporary dependency):
pkg install openssl pkg install fpc-libcurl-3.0.2For ArchLinux, there is a Red package there.
For step by step instructions on compiling your first script, please find them here.
Install Red using a package manager
choco install red
