See also my related posting in the list: It seems that guile can't
find the dll for readline support (the error message 'no code' seems
to indicate that guile can read (ice-9 readline) but can't load the
dll:
;; ice-9/readline.scm

;; Line 38
  (dynamic-call "scm_init_readline" (dynamic-link "libguilereadline.so")))

I was able to fix this problem by running guile in an environment where
'/usr/local/lib' is in 'LD_LIBRARY_PATH' (my $prefix for guile being
'/usr/local'), but i consider this only a workarround. 
Regarding Marius' suggestion in a previous mail: i _did_ run ldconfig
manually after module installation, without the wanted effect:

ldconfig: /usr/local/lib/libconstraints.so.0 is not a symbolic link

  debian:/etc/X11/pwm# exit
  address@hidden:/etc/X11/pwm$ guile
  ERROR: In procedure dynamic-link:
  ERROR: file: "libguilereadline", message: "file not found"
  address@hidden:/etc/X11/pwm$ 

Or, interactive:

  address@hidden:/etc/X11/pwm$ guile -q
  guile> (use-modules (ice-9 readline))
  ERROR: In procedure dynamic-link:
  ERROR: file: "libguilereadline", message: "file not found"
  ABORT: (misc-error)
  guile> address@hidden:/etc/X11/pwm$ 

I would like to suggest that guile adds 'pkglibdir' (which is known
to the guile runtime) to libltdl's search path.

/* file: dynl.c */

static void 
sysdep_dynl_init ()
{
  lt_dlinit ();
  lt_dladdsearchdir(PKGLIBDIR);
}

Where PKGLIBDIR is the path to guiles package library dir. This 
information is available in 'libpath.h'.
This might save some users some headache .... ;-)
