All now fixed.

Brian C. Grayson post gave me the information I needed.

I had to copy ld-linux.so.1.8.2 from linux. So my /emul/linux/lib now looks like

lrwxr-xr-x  1 root  wheel      13 Apr 26 00:29 ld-linux.so -> ld-linux.so.1
lrwxr-xr-x  1 root  wheel      17 Apr 26 00:29 ld-linux.so.1 -> ld-linux.so.1.8.2
-rwxr-xr-x  1 root  wheel   99308 Apr 26 00:28 ld-linux.so.1.8.2
-rwxr-xr-x  1 root  wheel   59305 Apr 23 12:33 ld.so
lrwxrwxrwx  1 root  wheel      14 Apr 25 04:25 libc.so.5 -> libc.so.5.3.12
-rwxr-xr-x  1 root  wheel  583795 Apr 23 12:23 libc.so.5.3.12

As Brian pointed out the man pages do not mention ld-linux anywhere.

Many thanks to all who have helped me.
