I'm looking for a simple way to HTML encode a string/object in Perl. The fewer additional packages used the better.

HTML::Entities is your friend here.
use HTML::Entities;
my $encoded = encode_entities( "foo & bar & <baz>" );
Which do you need to encode, a string or an object? If it's just a string, then you should just have to worry about encoding issues such as UTF-8, and CGI::escape will probably do the trick for you. If it's an object, you'll need to serialize it first, which opens up a whole new set of issues, but you might want to consider JSON-encoding it.
PS. Although since I can't find any recent documentation on this method (it's actually imported from CGI::Util and is marked as "internal"), you should probably use escapeHTML() as daxim points out in his comment: http://search.cpan.org/perldoc?CGI#AUTOESCAPING_HTML
