Subject: Strange Integer() behavior

I am learning Ruby and have encountered an error on a call to 
'Integer("039")' in 
gems/ruby-web-1.1.1/lib/web/htmlparser/sgml-parser.rb while working on a 
little screen scraper project.

Could someone please explain why the first three examples below succeed, 
but the fourth fails?

patrick-joyces-computer:~/projects patrick$ ruby -e 'Integer("07")'
patrick-joyces-computer:~/projects patrick$ ruby -e 'Integer("7")'
patrick-joyces-computer:~/projects patrick$ ruby -e 'Integer("8")'
patrick-joyces-computer:~/projects patrick$ ruby -e 'Integer("08")'
-e:1:in `Integer': invalid value for Integer: "08" (ArgumentError)
        from -e:1

It seems that "01" - "07" and any numbers without a leading zero work, 
but any number greater than 7 with a leading zero throws an 
ArgumentError.

Any advice would be greatly appreciated, as my program is failing on a 
certain page I am trying to scrape within the ruby-web gem and I am no 
where near confident enough to start messing around with those 
libraries.

On the off chance that this is a versioning issue I am running Ruby 
1.8.4 on OSX 10.4.6.

Thank you in advance for your help.
