After a successful make of all the XEmacs parts, when I issue the command make install I get (after a bit of elc creation and such): Wrote /Users/royar/src/xemacs/lisp/mule/custom-load.elc Building finder database ... ./xemacs -no-packages -batch -eval "(setq finder-compile-keywords-quiet t)" \ -l finder -f finder-compile-keywords Delete excess backup versions of /Users/royar/src/xemacs/lisp/finder-inf.el?
