Hmm I've..done

I move mplayer to /usr/bin/ (as root)
config to /home/user/.mplayer/ (as user)
menu.conf to /etc/mplayer/ (as root)

Yet when I try to use the GUI for mplayer (the one that comes installed with whatever is in extras [I left it there and just installed this on top) nothing happens

A terminal process for command mplayer says

"mplayer: error while loading shared libraries: libungif.so.4: cannot open shared object file: no such file or directory"

Help?
