 I would probably just uninstall 19.0 from wherever it was installed (i.e.
sudo apt remove or whatever the command is for the reverse on a package
manager you might have used) and re-build it with kerl. I think this would
be easier than figuring out where all the parts are and moving them into
kerl.

The quickest workaround might also just be to make the kerl paths come
before the other ones in your $PATH environment variable, which tends to
dictate the lookup order of executables on your filesystem.

Regards,
Fred.
