problem with gnu emacs

["Zach Uram" <netrek@gmail.com>]

When I run emacs I see this error:

emacs: /usr/local/lib/libpng12.so.0: no version information available
(required by emacs)

It happens even if I just open an empty buffer or a text file. Running
in console.

This is a Debian 4.0 system and the package versions installed are:

bach:~# dpkg -l|grep emacs
ii  emacs                      21.4a+1-3etch1                  The GNU

bach:~# dpkg -l|grep libpng
ii  libpng12-0                 1.2.15~beta5-1                  PNG
library - runtime
ii  libpng12-dev               1.2.15~beta5-1                  PNG

This is weird because I don't see what a PNG library has to do with
running emacs in a console!
