It looks like you've misunderstood, you have run your lisp implementation, when you are meant to run the exercism client (which is a "go" program, but is presumably compiled)

I have absolutely no idea what that means ... its so frustrating. Can i pay someone to go through Paul Graham's Ansi Common Lisp with me in person ?

I've not used exercism but I've RTFM

exercism uses a command-line client to download the exercises. This program is not a lisp program, it's just a binary to install for your platform (windows/linux/macos) and then run from a terminal.

Personally I started with CL with "On Lisp" rather than "ANSI Common-Lisp", but I had several programming languages under my belt by that point.
