[CentOS] screen

Hi - under CentOS 5, has anyone be able to get the vertically splitting 
under screen to work?

I downloaded the latest screen-4.0.3 and the

   wrp_vertical_split_0.3_4.0.2.diff.bz2

patch for vertical splitting and I still can't get it work.

^A | doesn't do anything.

Horizontal splitting works fine.
