I don't think that error is caused by the missing symlink, but then I don't know what the problem is and how to solve it. Unfortunately, I don't have any experience with AMD64 systems yet.
Note that the error with libfglrx_gamma.1 is harmless. You need to solve only the other one.
But I don't understand from *which* working directory this command should be run: ln -s lib /usr/X11R6/lib64
From any, as the destination is an absolute path. That command creates a relative symlink /usr/X11R6/lib64 that points to lib in the same directory.
