2 KDE sur la même distrib?

After installation you have to set some variables allowing your system to find
KDE binaries and libraries and KDE to allow to find its own files, for Bash:
 
  export QTDIR=~/kde3.5-beta2
  export KDEDIR=~/kde3.5-beta2
  export KDEDIRS=~/kde3.5-beta2
 
  export LD_LIBRARY_PATH=~/kde3.5-beta2/lib
  export PATH=~/kde3.5-beta2/bin:$PATH
 
Setting KDEHOME too, e.g. "export KDEHOME=~/.kdetest", will tell KDE to save
your settings to this directory and leave default ~/.kde directory unaffected.
