Ideally every gem (or nearly every gem) that works with Ruby 1.9 should work
with MacRuby. Browsing the homepage at
http://mechanize.rubyforge.org/mechanize/ it appears that Mechanize is still
tied to Ruby 1.8.7. However, if you can get it working with Ruby 1.9.2 and
it still doesn't work with MacRuby, then that would indicated a bug. A
reduced test case would be desirable, but bug reports are always welcome.
Cheers,
