Quake Darkplaces Water problem

[Polo1]

I have just installed DarkPlaces Quake in Fedora 12.
The installation was fine and so was the setting of the game as the hardware was compatible with it.
But I realized that the surface of the water and slime is black. Even though I have tried adjusting some video settings, no luck!

Can anyone help??

First of all, do you have vised maps?
Have you turn "r_water" on?
