Something like this perhaps:

(condition-case err
    (progn
      (cond
       ( (equal emacs-version "21.3.1")
         (setq custom-file "~/.emacs-cust-21.3.el"))
       ( t
         (setq custom-file "~/.emacs-cust-cvs.el")
         ))
      (when (file-exists-p custom-file)
        (load custom-file)))
  (error
   (lwarn 'my-emacs :error "Error loading custom:\n  %s" 
(error-message-string err))))
