`make install' on Mac OS X silently corrupts existing /Applications/Emacs.app

[Gregory Nathan Price]

I downloaded `emacs-22.1.tar.gz' from gnu.org, and following the
instructions in `mac/INSTALL' ran `./configure --enable-carbon-app';
`./make'; `sudo ./make install'.

Before doing so, I had a working Emacs in `/Applications/Emacs.app',
from Seiji Zenitani's widely-distributed build of a 2006 CVS snapshot.
(Working, but lacking some bugfixes which I was eager to obtain.  Thanks!)

After doing so, I had a chimera:

$ l /Applications/Emacs.app/Contents/
total 12
-rw-r--r--    1 price  admin    25 Aug 19  2006 .cvsignore
-rw-r--r--    1 price  price  3689 Jan 27  2007 Info.plist
drwxr-xr-x    3 price  admin   102 Aug 19  2006 Library
drwxr-xr-x    5 price  price   170 Sep 18 15:55 MacOS

drwxr-xr-x   15 price  price   510 Jun  2 07:19 Resources

This chimera didn't work correctly; for instance, python-send-buffer fails:

Python 2.3.5 (#1, Jan 13 2006, 20:13:11) 
[GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin

    import readline
ImportError: No module named readline
>>> >>> Traceback (most recent call last):

NameError: name 'emacs' is not defined
>>> >>> 

The file `/Applications/Emacs.app/Contents/Resources/etc/emacs.py'
does not exist in a clean install from emacs-22.1.tar.gz;
presumably it should not have been loaded.


Of course moving /Applications/Emacs.app out of the way is all it took
to make a clean install.  But Emacs' `make install' should notice an
existing installation, and stop short rather than (a) destroy the
existing installation and (b) produce a part-working chimera.

Thanks, best,
Greg Price
