    This is likely a symbol in the gfortran compiler libraries.

   Are you linking your application code against all the libraries it  
needs to be linked against? In the PETSc directory run make  
getlinklibs make sure all the libraries are listed in your makefile or  
use a PETSc makefile as a template.

    Or this is coming from the fact that you are using shared or  
dynamic libraries. If you don't need shared libraries then run PETSc's  
config/configure.py with --with-shared=0
