You can get the guile 1.8.8 binary, using the GNU Guix package manager. To install this package manager on popular distros (such as debian) use the distro’s package manager.
For example on debian based distros you install it using the command:
sudo apt install guix
The GNU Guix package manager does not interfere with the host package manager. It installs binaries/libraries/etc. in separate folders.
It takes a while to install Gnu Guix and you have to edit your .bash_profile to add the binaries to your path. Here is a tutorial by the System Crafters guy.
After the guix command is installed, you can run:
guix install email@example.com
I tested this on Ubuntu 22.10.
Hope it helps.
EDIT: Some extra steps are neccessary to setup guix, see the linked video.
