Good news, this is fixed by 50ea3135e0948a042cd3b899e970f6ade291a0c2!

As noted in the commit log, this issue stemmed from a change in
#:autoload semantics in Guile 3.0.  In 3.0, the line:

  #:autoload (gcrypt hash) (port-sha256)

means that only ‘port-sha256’ is imported.  Conversely, in 2.2 (which is
the Guile version used by the ‘compute-guix-derivation’ program above),
that #:autoload line means that all the (gcrypt hash) bindings are
imported.  That includes the ‘sha256’ bindings, which would thus prevent
matching the ‘sha256’ literal in the ‘origin-compatibility-helper’
macro.  Terrible!

Ludo’.
