In repository , developers have compiled the software from source into binary suited for your distro & tested it too.
Still , if you are interested in doing manually then
usually , the sequence to run in terminal is
Code:
mkdir tarballs_extracted #let us be systematic
cd tarballs_extracted
tar -xvzf absolute-path-to-.tar.gz-file
cd folder-just-created
./configure
make #if no errors (like gcc , software library etc. missing) occur in above
sudo make install
Also , always post your distribution version and relevant file details.
Hope , that helps.
