A runtime error such as this suggests that you compiled with one compiler
and did not statically link but then when running your LD_LIBRARY_PATH and
PATH variables point to a different set of compiler libraries.

E.g. you compiled with ifort v9 but your .cshrc file is setting up your
environment for the v8 compiler.

Check LD_LIBRARY_PATH and PATH on your machines at runtime and check they
point to the correct place.

You could also recompile your code statically. That is add the -static
option to the configure script and then recompile amber. In this way you
won't have to worry about the wrong libraries being specified at runtime.

All the best
