I just managed to reproduce this very same error message after
downgrading to commit a67c00f4f7ee0a70fce14a7e1907cce332c85813 (I lost
the previous system a couple of days ago), and it threw this error after
trying to reconfigure.  Given that it is complaining about srfi-1, I
disabled everything that was relevant to it, and it still fails.

Just to be sure I'll paste my error message again:
