You don't run KDE 2.x ?????? shame on you ;-) .....yes you can run KBear without running KDE, but you got to have the kdelibs installed though. (see Requirements Section )
5.2 KBear complain about that it can't find the file: sitemanager when it's started for the first time.
You probably haven't set your paths correctly.
Make sure you have set these environment variables in the file: .profile (or .login, depending on your shell, for bash the file is .bash_profile) in your home directory. (Create the file if it is not there already.)
KDEDIR=full_path_to_where_kde2_is_installed QTDIR=full_path_to_where_your_qt-2.2.2_is_installed PATH=$KDEDIR/bin:$QTDIR/bin:$PATH MANPATH=$KDEDIR/man:$QTDIR/man:$MANPATH LD_LIBRARY_PATH=$KDEDIR/lib:$QTDIR/lib:$LD_LIBRARY_PATH LIBRARY_PATH=$LD_LIBRARY_PATH CPLUS_INCLUDE_PATH=$KDEDIR/include:$QTDIR/include:$CPLUS_INCLUDE_PATH export KDEDIR QTDIR PATH MANPATH LD_LIBRARY_PATH LIBRARY_PATH export CPLUS_INCLUDE_PATH
After this logout and in again( or make sure your .login script runs again). Then recompile and reinstall KBear, don't forget to run
% make distcleanand make sure the file config.cache is removed before recompiling
If you have used an earlier version of KBear ( beta3 or earlier) you have to manually remove the file $HOME/.kde/share/apps/kbear/sitemanager. This is because changes made to SiteManager that make the old one incompatible with the new. If this doesn't help, you probably haven't set your paths correctly. See: KBear complain about...
