(use-modules (ice-9 slib)) is archaic and doesn't work anymore.

On Unix systems, "slib guile" will run Guile with SLIB.

Otherwise, set SCHEME_LIBRARY_PATH to the SLIB(3b1) directory.  Then:

  guile -l ${SCHEME_LIBRARY_PATH}guile.init

What makes you say so?  It's supposed to work (info "(guile) SLIB").
The module was fixed (see `ice-9/ChangeLog-2008' entry dated 2007-10-02)
and the doc was updated for Guile 1.8.3 (tested with SLIB 3a3).

Thanks,
Ludo'.

SLIB-3a3 was released over 3 years ago; SLIB-3b1 was a major revision
from SLIB-3a5 in 2008.  SLIB-3a3 is no longer supported.

I don't control Guile documentation.  Its unfortunate that it
references a very out-of-date SLIB.

Thanks - but I still get the same error when I use either of those
methods.  

Actually, with guile 1.8.6, it seems that I still need to
(use-modules ((ice-9 slib)) after the invocations above;
I think because of the version number test at
the beginning of guile.init.  With guile 1.8.1, the invocations
above work, but I still get the conflict with guile's built-in
list->array.

Has `guile.init' changed since then?

For the record, since Guile 1.8.3 `(ice-9 slib)' does almost nothing:

  http://git.savannah.gnu.org/cgit/guile.git/tree/module/ice-9/slib.scm

It proved to be sufficient back then:

Use-modules doesn't work on my development machine; but that's not
your problem.  The list->array issue was addressed last year, but I
haven't made a release since then.  The following message includes a
patch to fix the problem.

 | SLIB's `array' module (and possibly others) from SLIB 3b1 appears
 | to be partly inaccessible from Guile 1.8 as reported here:
 | 
 |   http://permalink.gmane.org/gmane.lisp.guile.user/6527
 | 
 | Any idea what to look for?

  In /home/ludo/soft/lib/slib/byte.scm:
    61: 6  [list->array 1 #u32(32) (0 0 1 1 0 1 0 1 0 ...)]

  /home/ludo/soft/lib/slib/byte.scm:61:3: In procedure list->array in expression (list->array 1 (A:fixN8b) ...):
  /home/ludo/soft/lib/slib/byte.scm:61:3: Wrong number of arguments to #<primitive-procedure list->array>

Guile-1.8.1's list->array takes two arguments; but it should take
three (see http://srfi.schemers.org/srfi-63/srfi-63.html or
http://swiss.csail.mit.edu/~jaffer/slib_7.html#SEC193 )

  guile> (array->list (list->array 2 '((0 1) (1 4))))
  ((0 1) (1 4))

  guile> (array->list (list->array 2 '#() '((0 1) (1 4))))

  Backtrace:
  In standard input:
     8: 0* [array->list ...
     8: 1*  [list->array 2 #() ((0 1) (1 4))]

  standard input:8:14: In procedure list->array in expression (list->array 2 (begin #) ...):
  standard input:8:14: Wrong number of arguments to #<primitive-procedure list->array>
  ABORT: (wrong-number-of-args)

Appended is a patch which corrects list->array, as well as providing
missing array->vector and vector->array.

Thanks for your bug report.  The development version is updated:
http://groups.csail.mit.edu/mac/ftpdir/users/jaffer/slib.zip

Also, the CVS repository is updated:
https://savannah.gnu.org/cvs/?group=slib
