How to you *really* use this in MediaWiki?

I have spent many hours trying to get FCK editor working in MediaWiki with little luck. I have been able to follow the most basic instructions and get a lot of FCK working. What I cannot get working are the Browse dialog buttons in the link and image buttons. These buttons just won't show up. When I try to sample php file FCK both dialog work correctly. I assume I must be missing some setup step. All I had to do to get the FCK showing up was to add
require_once $IP . "/extensions/FCKeditor/FCKeditor.php"; to my LocalSetting.php. Like I said before, the Browse buttons will not be visible.

I cannot get the stock FCKeditor to work at all so I have been using the FCKeditor+MediaWiki version. I have looked at the instructions at: http://mediawiki.fckeditor.net/index.ph ... tion_guide and cannot make any sense of them. No line numbers are given and some of the lines that need changing don't seem to be in the code as written.

Has anybody gotten MediaWiki and some version of FCKeditor correctly working together? If so, are there any clear and complete instructions on how to do this?
