Thanks for making the update. I tested building both racket and 
racket-minimal on x86_64, and was able to do a lite REPL session in each 
one without problems.

Its nice that you CS building patch made it into upstream. 
Congratulations.

Not related to the update, but I noticed `guix lint` complain about the 
racket synopsis (it begins with an article). I think we could just drop 
the 'a' and leave the rest of it as is and it would still make sense and 
satisfy the linter.

Best,
Jack
