Puzzling error

[Kevin Ellwood]

Ah.  I think I have confused you guys.  I am using the most recent version
pf Petsc (ie. 2.3.3 p13).  I am trying to get my old code (which I made
using 2.0.22) up and running.  I have updated most everything and I am
trying to run for the first time.  Given what you said, I am guessing that I
have messed up in a way the causes KSPRegisterAll and KSPRegister not to be
called.

Thanks
Kev
