Hey,
I don't know this errors, very weird indeed. As a tip:
you may download quicklisp from ECL at first run like:
(require 'ecl-quiclisp)
To call the first restart you have to type a symbol in the keyword package ":r1", to call the second restart use ":r2" etc.
I'm sorry, but your errors doesn't sound even close to familiar. I suspect that you may have some weird quicklisp version or ECL doesn't have permissions to do something (ie write a file).
Best regards, Daniel
