The ccl programs in w3m-ems.el, that provide the `w3m-euc-japan'
coding system and the `w3m-iso-latin-1' coding system for Emacs
21 and 22, cause this error in Emacs 23.  It is possible to
improve the source code so that it does not cause an error in
all the versions of Emacsen that emacs-w3m supports.  However,

why I recommend rebuilding the elc files is that things causing
errors are not only them.  The typical one is the macro
`detect-coding-with-priority', of which the expanded versions
made by Emacs 22/23 are incompatible with Emacs 23/22 mutually.
There will probably be other incompatible things, though I have
not scanned all over the emacs-w3m source code yet.

In addition, I believe there will possibly be the ones other
than emacs-w3m that cause such a trouble.  So,

I think the best way is to install the PACKAGEs to

/usr/local/share/emacs/VERSION/site-lisp/PACKAGE/

for each VERSION of Emacs.  Actually I've been doing so because
I have various versions of (X)Emacsen installed.
