I'm not too sure about why the RubyForge upload isn't working,
maybe Tom can provide some insight to that.
That being said, is there any reason why you need to update the
RubyForge stuff in the first place? Especially now that http://rubydoc.info updates docs for
every pushed gem automatically, it seems like a hassle to do things
the old way. :)
Are the documentation pages always built on the fly (processing
circle turning on the screen)? That would mean that Google indexes
them less. A google search for "spreadsheet ruby" still yields me
the rubyforge-page. Until I get to see the documentation on
rubydoc.info it does take some time.
