I've uploaded an x86_64 rpm here [1], the srpm is here [2]. To reproduce 
the problem, first download the foil gometry [3], then run xfoil from a 
terminal, and type

and at the following "Enter airfoil name" prompt, type


Upon pressing enter, the Xplot11 window should open, showing the 
cross-section of the foil.
