I also tried : yum --disablerepo=dag install compat-listdc++
and got this message:
Setting up Install Process Setting up Repo: livna-stable http://rpm.livna.org/fedora/3/i386/yum/stable/repodata/repomd.xml: [Errno 4] IOE rror: HTTP Error 404: Not Found
Looks like another bad URL. The file it's looking for appears to be: http://rpm.livna.org/fedora/3/i386/yum/stable/RPMS/repodata/repomd.xml rather than: http://rpm.livna.org/fedora/3/i386/yum/stable/repodata/repomd.xml
So you'll need to fix your yum configuration for livna.org as well as the one for Dag's repository. Where did you get these configurations from?
