I's very easy. Just recompile the module and then perfom the command

	BootLinker.Link LinuxOberonCore := ...

in the x86.Linux.Tool. 

The right place to fix Aos would be:

	x86/Linux/Glue.Mod:
		libcname = "libc.so"		==>	libcname := "libc.so.6"
	x86/Linux/Unix.Mod:
		libc := Dlopen( "/lib/libc.so", 2 )	==> libc := Dlopen( Glue.libcname, 2 )	


Or fix it in Linux with
	
	ln -s  /lib/libc.sp.6  /lib/libc.so
