I am using

L-Ubuntu 12.04, Lilypond 2.18.2,
Guile 1.6, then 1.8 (from Ubuntu repository), then
Guile 2.0.11 (from gnu.org)

The manual ( Contributor's Sec 10.7.3 )
says to do             \include "guile-debugger.ly"
This produces

Parsing...
/usr/local/lilypond/usr/share/lilypond/current/ly/guile-debugger.ly:39:2: error: GUILE signaled an error for the _expression_ beginning here
#
 (use-modules (ice-9 readline))
readline is not provided in this Guile installation
/usr/local/lilypond/usr/share/lilypond/current/ly/guile-debugger.ly:40:2: error: GUILE signaled an error for the _expression_ beginning here
#

 Guile debugger for Lilypond
 For help enter (debug-help)

#
 (use-modules (scm guile-debugger))

guile>


I get the same errors with all 3 versions of Guile.
I could not find anything relevant either in Google or guile users.

Thank you
