Exactly, that's a Mac OS X issue: webrick-webdav supports protocol  
version 1.0, while Mac OS X wants the server to support v2.0 in order  
to let you write on that share.
I had the same problem as yours, but I couldn't find enough  
documentation anywhere (about webrick-webdav or about the version  
required by OS X) so I started reading webrick-webdav sources and  
comparing the traffic dump with an apache webdav module and I found  
out this version issue.
Actually I think that the only difference between 1.0 and 2.0 servers  
is that the latter ones support LOCK methods, which allow to lock  
files (exclusive or shared locks). I didn't need this, so I just  
inherited from WebDAVHandler:

module WEBrick
   module HTTPServlet
     class WebDAVHandlerVersion2 < WebDAVHandler
       def do_OPTIONS(req, res)
         super
         res["DAV"] = "1,2"
       end
     end
   end
end

So I started using WebDAVHandlerVersion2 instead of WebDAVHandler. In  
fact, on the source code of WebDAVHandler there is a commented out  
'res["DAV"] = "1,2"' line...
It worked, I'm quite sure I could write to that share, but right now  
it seems like it doesn't work very well with OS X: I get strange  
errors when writing into a file or creating a new one.
Some time ago I wrote a page about my experiments with WebDAV, since  
I couldn't find enough documentation: http://gmarrone.objectblues.net/ 
cgi-bin/wiki/WebDAV_-_Linux_server%2c_Mac_OS_X_client .
I summed up almost everything in this mail, but maybe you can find  
something useful over there :)
It isn't up to date, though: I don't describe the errors I get now  
with that solution.

Please let me know if your Mac OS X is able to write without any  
error on that modified version of webrick-webdav :)
