Date: Fri, 12 Mar 2010 23:17:56 +0100 [thread overview]

A few days ago I found a misbehavior related to the list-color-display
command. I have made further investigations and finally figured out,
that the problem is caused by the build process, I have used (by accident).
When I run the build commands as descibed in nextstep/INSTALL everything
works fine:
./configure --with-ns
make
make install
And this is the command sequence which builds a Emacs.app with the
described problem:
./configure --with-ns
sudo make
sudo make install
