I'm having problems with com.gigamonkeys.binary-data in sbcl (I have
similar problems in clisp, but I debug more in sbcl).

Note, in the following sequence of events 'iso-8859-1-string,
'iso-8859-1char and 'generic-string are all supposed to be 
defined eql specializers on the first argument to the read-value method:

 
CL-USER> (require :com.gigamonkeys.binary-data) 
;loading system definition from
; /home/singollo/.sbcl/systems/com.gigamonkeys.macro-utilities.asd into 
; #<PACKAGE "ASDF0">
; registering #<SYSTEM COM.GIGAMONKEYS.MACRO-UTILITIES {A787029}> as 
; COM.GIGAMONKEYS.MACRO-UTILITIES
NIL 

CL-USER> (in-package :com.gigamonkeys.binary-data) 
#<PACKAGE "COM.GIGAMONKEYS.BINARY-DATA"> 

BINARY-DATA> (intern (string'#:generic-string)) 
GENERIC-STRING
NIL ;;<--not currently interned 

BINARY-DATA> (intern (string '#:ISO-8859-1-STRING)) 
ISO-8859-1-STRING 
NIL ;;<--not currently interned 

BINARY-DATA> (intern (string '#:ISO-8859-1-CHAR)) 
ISO-8859-1-CHAR 
NIL ;;<--not currently interned 

BINARY-DATA> (read-value 'iso-8859-1-string *some-binary-stream* :length 1)

gives the error message:

"There is no class named ISO-8859-1-STRING."

This means the default read-value method is getting called instead of the
one defined in the define-binary-type macro

The weird thing is slime list all the keyword args as if the method was
defined.

BINARY-DATA> (lisp-implementation-version)
"1.0.7.37"

Anyone have any ideas?

Ok, I'm an idiot. The datatypes are in
:com.gigamonkeys.binary-data.common-datatypes.  I like Peter Seibel work,
but the package naming discipline almost seems sadistic.
