Just to rule out the obvious things:
did you perform a clean rebuild?
ie.: make clean, or git clean -fxd, the bootstrap, configure, make

Also could you send the patch containing your additions?

My guess is that the Guix feature that auto-suggests what module to
import when there is an unbound variable error is matching the list
caught from the exception but its patterns don't cover it.  Maybe it has
an extra element or something?

Also, getting the commit from git that yours builds on might be helpful.
