Hello,
I’m at a point where I need to use an older version of ROOT to do some work. I’m on Ubuntu 11.10 and I first had to modify the configure script to tell it where to find libX11 etc., however when I go to make -j4, it gets to a point and make throws the error:

I’m at a bit of a loss. I’ve read in various posts that only version 5.32 is supported on the latest Ubuntu release but there must be some fix 
Does anyone have an idea?
Thanks
