problem with Encoding::encoding_from_html_document

Hi,
I am trying to use HTML::Encoding to determine the encoding of an 
arbitrary url. I have installed the latest version of all appropriate 
perl modules and use perl 5.8.7 (although the installs are not clean 
- I have done numerous updates during the years). It would appear 
that I am having problems in cases where the encoding is to be 
determined from Encoding::encoding_from_html_document. Thus for 
instance, the url "http://www.h-opera.com" does not provide explicit 
encoding in which case the "Encoding.pm" module spits out a list of 
warnings (enclosed below) when I run 
Encoding::encoding_from_html_document.  Thankful to anybody who can 
help. By the way the encoding of the above url is MacJapanese as 
determined by Encoding:: encoding_from_first_chars.
