Here all the compiler did is link, you do not see it try to compile
new2oldparm.f. This suggests that the current source directories you have
are not clean. I.e. they contain object files that were compiled with
another compiler. Hence when g95 tries to link it finds that the naming
convention it uses doesn't match that of the compiler that originally
compiled the object files.

You can try doing.

make clean

That should work. Failing that I would make sure you start with a completely
clean tree. Untar the amber9.tgz file from the amber cd and use that. You
should also apply all the bug fixes from the amber website first.

All the best
