Thanks for this analysis!
The loko.scm file was not recompiled so it searched chez.scm for a
variable named chez-scheme-for-system, which is now a syntax
transformer. But compiled files have already completed the expansion
phase, so this means that a syntax transformer is invalid. This will not
cause a problem for `guix pull` because guix rebuilds itself from
scratch when it gets updated.

Very interesting! I hadn't realized that problem with dependency
tracking existed: it might explain some issues I've struggled to
reproduce in the past. It's also given me several surprises about
Guile's implementation of phases: for one thing, apparently
(define-syntax x 42) expands to (define x (make-syntax-transformer 'x
'macro 42)). I wouldn't have expected a macro to create a value that
would exist at runtime.
