Finally I have a sensible editor installed on my Intel iMac. It's called Carbon XEmacs (aka. just emacs :)
All thanks to Andrew Choi. He's prepared two patches that makes this possible. The version I got was XEmacs-21.5.23 plus two additional patches from Andrew for Intel support and proper "Quit Application" connection with the OS. Thankfully nothing was difficult because everything went smoothly without any error messages anywhere. I did have to do some reading, searching and downloading. The hardest task was to find Andrews Carbon XEmacs site to just get started. If you also have an (Intel) mac os x and want to install XEmacs too, here are some notes on what I did:
xemacs-21.5.23.tar.gzfrom this site
xemacs-sumo.tar.bz2from this site
xemacs-21.5.23-carbon-b4.diff). Also download
quit-application-apple-event.difffrom the same repository.
sh < build-app.shfrom the
carbondirectory. Note: To do the patches, I found I had to use'-p1' for the carbon file and no
-pfor the smaller ones. You might need to
cdinto the correct directory.
XEmacs.app. Copy this manually to your Applications folder.
