1.make
2.make install

It gives this output

I had previously installed smplayer 0.5.21 without any problems..what should I do????

Looks like to me it is using the QT3 libs according to the fifth line from the bottom. What QT is installed.
rpm -qa | grep qt

probably need to specify on the ./configure like this pointing to the qt4 directory
./configure --with-qt-dir=

Actually downloaded the smplayer and read the install.txt docs. It describes the QT4 setup the way it needs to be.
