You are likely using a version of AUCTeX byte-compiled with GNU Emacs
(it is conceivable that problems like that could happen also because
the version of XEmacs used for byte-compilation of the package has
been too advanced, in that case using byte-compile-file first on
prv-xemacs.el and then on preview.el should help).

So it would appear that you have something wrong in your XEmacs
load-path.

More likely had one too many...

That should be sufficient.  I hope you previously deleted any old
copies of preview-latex and/or AUCTeX.

It does not say that for XEmacs IIRC.  For XEmacs, just installing the
package should work.
