[Xquartz-dev] Reverting from 2.3.0-rc4 to 2.2.2

Gentlepeople, Please forgive the user-ish question, but how do I cleanly revert from 2.3.0-rc4 to 2.2.2? I mistakenly installed the 2.3.0 variant after upgrading to 10.5.3, and have run into various issues (stuck ctrl and lack of .xinitrc invocation in particular). I noticed the file list in the .bom under the Receipts directory ... should I simply remove everything that's a file or an empty directory listed there and do a clean re-install of 2.2.2? Do I need to go back and install the virgin Leopard X11 package first? Is there a script hidden somewhere that can do this easily? Again, my most abject apologies for bugging the developers for such a dumb-user question! Thanks very much! - Jim
