[aur-general] Problem with package installation

Hi everyone, I'm new to the community and I would contribute by adopting coreutils-acp package. I've got problem to install it with 'pacman -U' because of the already existing packages. Is there any trick to avoid this problem ? here is the install log coreutils-acp: /bin/cat exists in filesystem coreutils-acp: /bin/chgrp exists in filesystem coreutils-acp: /bin/chmod exists in filesystem coreutils-acp: /bin/chown exists in filesystem coreutils-acp: /bin/cp exists in filesystem [...] Thank you very much
