[CentOS] Compile error

[Joe Landman]

Hi Sam:

   Some library somewhere is using a different ABI than you expect.  Do a

	file wrf_user_fortran_util_0.o

and against any of the shared/static objects you are linking against. 
Make sure you have the right -L options.  I got this when I had a stale 
build of something. I had to rebuild the application after cleaning out 
the old libs/objects (a simple make clean often helps).
