[racket-dev] Installing Optimization Coach broke Racket's reader

Setup finished, still had the reader error. I removed Optimization 
Coach, cleaned, and ran setup again. My reader is still broken.

"git status" shows no changes in my local repo. "raco pkg show" shows no 
packages. "raco link -l" shows no additional links.

Where are these invisible craptastic things that are breaking my stuff?
