Version 61.2 is out.  Can you see if that still works?

That's an unusual input.  Can you add a comment about why it's needed?

Same here: please use the existing bootstrap phase if possible, or
replace it.

Please use full sentences in descriptions.  E.g. "This package provides
a ...".

Please add comments when the licensing situation is not clear cut.  I
had a look, and while COPYING says LGPL2.1, most of the source headers
were GPL2.

In that situation GPL2 "wins", so I'd write this as:

  ;; COPYING says LGPL2.1, but many source files are GPL2 so that's
  ;; the effective license.  Note that some files under ccan/ are
  ;; covered by BSD-3 or public domain, see the individual folders.
  (license license:gpl2)))
