I've already answered this question. I can't help you if you ignore
my suggestions.
The runtime linker is finding the 32-bit version of libgfortran.so.3
but you are trying to run a 64-bit program.
There are a number of ways to tell the dynamic linker how to find the
right library, see
http://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dynamic_or_shared.html#manual.intro.using.linkage.dynamic
You need to tell the runtime linker how to find the right library files.
Run "ldd ./int2lm_seq_v1.18" and it will show you the file it's using.
You need to make it find the right file, that you installed when you
installed the newer version of GCC.
