    recommend user to install missing engine(s)
    
    as in most case - except Hexen - there should only one recommended engine
    this sentence is writen in singular.
    If there were a tool that could install local & remote packages at once
    (dpkg -i data.deb + apt-get install engine); this coudl be used
    to avoid to run 'su' twice. A other option is to use
    a two line temporary shell script, but it's ugly.
