[comments]
* intsalled apache server by using 'apt' command of ubuntu, however, it turned out
  different from normal way of configuration
* ubuntu serves its own of configuration
* it could take more time to figure out how to install others modules and usse it
* finally, installing the apache server in the standard way seems recommendable

     - sudo make

     * before installation, build-essential sould be installed in advance
       ; sudo aptitude install build-essential
