I have noticed that tarballs are meant for installing software from source . It takes some time to compile it .
The quicker & easier way is http://forums.linuxmint.com/viewtopic.php?t=97158
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
mkdir tarballs_extracted #let us be systematic
tar -xvzf absolute-path-to-.tar.gz-file
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.
