I tried your suggestion, and it appears that with LD_ASSUME_KERNEL=2.4.1 
the things quit complaining about the library. I have no idea what is 
happening in that respect, but something happens. I'm not seeing the 
"normal" message from real.exe about not having an input namelist 
however, so I may or may not work. running the exe's does however give 
me a "starting wrf task 0 of 1", and the other .exe's , real/ndown, 
etc., also do the same thing. I'll have to muck around in the startup 
script and see what happens when changing those. Also, since mpi is not 
running, nor do I have OMP set, it *might* just take off and work. I've 
got to pass this info to my compadre in crime and let him know, as there 
maybe some other things to look at besides the message passing 
protocols. I really thank you for the suggestion.

On another note, you indicate perhaps we should not be using the tls 
version? Can you expand on that a bit as to why, and what the tls is?
