Compiler won't run under current Racket release

[0xacf]

It appears that some unstable libraries have been removed. Changing to the racket standard library versions is not difficult.

I was able to fix my build problems using this patch, thank you for fixing this Alan.

I know it's 6 years since this tree has been touched, but is there any way this patch could be applied upstream so others won't have to browse to fix build errors? Thank you.
