Which version of XCode on MacBook to run WO5.2.4?

Hello!

Maybe this issue is for this list but, I think some of you have the 
answers? I have been struggling with putting my development environment
which is WO 5.2.4 on a MacBook running.

First I installed the xcode 1.5 tools and then WO 5.2 and patched it to 
5.2.4 and installed xcode 2.2.1 on to of that.

I also installed eclipse RC7 and the latest wolips. WOlips runs like a 
charm and I would like to take this opportunity to thank the developers 
of this plugging for there great job on their spare/free time.

My problem is regarding the EOModeler. I'm not know able to set the JDBC 
adaptor info, actually the New Updated Model option and Set adaptor Info 
is grayed out from the drop down model option in EOmodeler. My theory is 
that when I installed xcode 2.2.1, it overwrote some files? and what I 
need is to get a copy of xcode 2.0 but it is not available from 
developer.apple.com. So I wonder if any of you have an old copy of xcode 
2.0 and maybe you could share it with me? I there send a link or I could 
provide you with an ftp account?

If I take the option Switch Adaptor and choose JDBC following message 
will raise

"Unable to load the JDBC adaptor: classForAdaptorNamed:: Unable to load 
the bundle for the adaptor named JDBC. The possible causes for this 
error are: the adaptor executable cannot be dynamically linked into your 
application, you are on PDO and have not linked the adaptor into your 
application, or the adaptor executable is not present on your host."

I do have my jdbc jar files on the correct spot as I can run my 
applications.
