Are you by change mixing object files compiled by an older version of
gfortran? Or do you have two different gfortran compilers installed
which are at a different path?

In the changelog I find for 2006-07-12:
* intrinsics/string_intrinsics.c (copy_string): Remove function.

This function was in gfortran 4.1.x (libgfortran.so.1.0.0) but has been
removed for gfortran 4.2.x/4.3.x (libgfortran.so.2 and .3).

Another thing you should check is that the library path is correctly set.

Is the file in /cern/2005/lib compiled with the same version of gfortran?

More helpful for us is the version number shown by gfortran -v.
