BTW: Its suspicious that you have to modify so many output files
[other than ones corresponding to ex56]

for ex:
 src/ksp/ksp/examples/tests/output/ex19_2.out       |  20 +-

This example does not use 'cheby' - but still you have to modify this file?

    added ex56 in snes, 3D linear elasticity using Plex on a cube
    
    clean up cheby fix
    
    small cleanup of noisy cheby
    
    fix ex56 init/fin error
    
    remove spaces
    
    fix complex build
    
    updated test for new cheby
    
    fixed test for new cheby
    
    merge makefile changed for ex56 and parmetis
    
    fixed bug in makefile
