you're running FC1, so i'll assume the .tar.gz that you downloaded is a source package. -- run
Code:
tar -zxvf <compressed package>
and that'll extract it. then read the <directory>/README and <directory>/INSTALL files which are commonly found
with install scripts, you usually just run those, otherwise it's usually
Code:
./configure
make
su
<passwd>
make install
--run from within the extracted directory
