(srfi srfi-26) must not be added to the imported modules: it would
import it from the host Guile, but the host Guile version may differ
between users, and thus the resulting derivation would also differ.

The right thing is to just (use-modules (srfi srfi-26)), which has the
effect of using that module from the Guile being used for builds.

Could you adjust it accordingly?

Thanks, and thanks for the bug fix!
