Bug#776644: texlive-xetex: xeCJK error message apparently prints wrong command

[Leonardo Boiko <leoboiko@gmail.com>]

Package: texlive-xetex
Version: 2012.20120611-5
Severity: normal

If I try to compile a document including \usepacakge{xeCJK}, but without
a main font command, xelatex prints this message:

    *************************************************
    * xeCJK warning: "no-CJKfamily"
    * 
    * It seems that you have not declare a CJKfamily.
    * If you want to use xeCJK in the right way, you should use
    * 
    * \xeCJKmainfont[...]{...}
    * 
    * in the preamble to declare the main CJKfamily.
    * 
    *************************************************

But if I use the suggested command, I get:
    
    ! Undefined control sequence.
    l.20 \xeCJKmainfont

The included example files don't use \xeCJKmainfont , they use
\setCJKmainfont .
