Bibledit can be installed from a Debian .deb package.
That should be all that is needed.
If the version of Bibledit that comes with your version of Debian is not the one you prefer, or not new enough, you can install a version from the Debian testing or Debian unstable repository.
Note: This is likely to be the case if you are using Debian Lenny, the current stable Debian release as of May 2009. The Bibledit packages in Debian testing (squeeze) and Debian unstable (sid) are much newer.
To add the Debian testing repository:
If you prefer to use a package from the Debian unstable repository, then the "Apt line:" text should instead be
deb http://ftp.debian.org/debian/ unstable main
Once your chosen repository is added to your system, you can add the Bibledit package from it using the Synaptic Package Manager as described above. It may require updated versions of some other packages too. If so, these will be automaticaly updated by Synaptic as part of the Bibledit package installation process.
Note: Unless you want to update your entire system to use everything in the repository just added, once you have installed Bibledit, you should use System -> Administration -> Software Sources and remove the repository that you just added. Advanced users can override this using the apt preferences file.
Support for installing packages is not given by the Bibledit crew. See http://www.debian.org/support for a wide variety of Debian support resources.
