Some eggs just don't install and the error messages are really bad at that point. Trying to install awful to develop a web api I had to give up, couldn't find a way of getting it installed on windows (no problem on OSX or Ubuntu 18.04)
Installed Portacle and (ql:quickload "hunchentoot") and was up and running in a few minutes.
A lot of lisp-languages could do with an equivalent to Portacle, an opinionated dev environment that you can install and just start coding, an area that Racket is excellent in.
