In order to compile and install KStars on your system, type the following in the base directory of the unpacked KStars distribution:
% ./configure --prefix=$KDEDIR % make % make install
Please don't forget the prefix argument to configure. If your KDEDIR variable isn't set, set prefix to whatever directory KDE is installed in. It's usually either /usr, /opt/kde or /opt/kde2. Also, make sure you do the last step as root. KStars uses autoconf and automake, so you should not have trouble compiling it. Should you run into problems please report them to the KStars mailing list <kstars-devel@lists.sourceforge.net>.
