It seems like some other commit may have broken the cycle in the mean
time. Here's what I had been seeing:
```
philip@avalon:~$ guix time-machine
--commit=ae88e30a0f8403e781f8b01262766cdc46b1018a -- show chez-scheme

```
I don't think anyone ever figured out where the cycle was. The tl;dr of
my long comment is that there wasn't a logical cycle yet, and I was
intending to have (gnu packages racket) import (gnu packages chez), but
not vice versa, for now.
raingloom had discussed more on IRC---I only happened to see a little of
it, but I could reproduce.
