kdelibs4c2a 4:3.5.6-4ubuntu2 (amd64 binary) in ubuntu gutsy

 This package contains all the shared libraries and common core binaries
 used by all KDE applications. You need these libraries and binaries to
 run KDE applications.
 .
 Several scripts included in kdebase-bin, related to the handling of SMB
 and NFS shares, require the perl-suid package to work properly.
 .
 If you are working with remote filesystems, you may find that fam
 is helpful in tracking filesystem updates. If you work only with local
 filesystems, then avoid fam (and gamin), since if they are not installed,
 KDE will use its own more efficient inotify (or else dnotify) system
 directly.
 .
 This package is part of KDE, and a component of the KDE libraries module.
 See the 'kde' and 'kdelibs' packages for more information.
