Install extension

Hi all, I want to add a stemmer extension on my php. I worked fine with windows platform and precompiled DLL. Now i have to switch to unix server and need to build it from source. But i am newbie on building from source. And want to get some helps. What i want is to add the extension "stem-php" avaible on this site http://www.tutorbuddy.com/software/ The source can download from here http://www.tutorbuddy.com/software/download.php/stem-php-1.2.1.tar.gz I read the README, have this few lines: ---------------------------------------- 4. How do you compile it? You compile it as you would any other PHP extension. On UNIX-like systems: 0. Unpack the source into /path/to/php/ext. 1. Run buildconf. 2. Configure using the --enable-stem argument. 3. Run make. ----------------------------------------------------------- However, i dont know where are "buildconf" and "make" ?? Thanks for advance Nowhereman
