Cygwin + insight + arm utils

Hello all, I have just installed cygwin and arm tools to do some arm assembly programming, but when i try to initialize insight with arm-elf-insight xxx.xxx I receive the message that arm-elf-insight cannot find cygncurses-8.dll. In my lib directory I have cygncurses-10.dll, but not cygncurses-8.dll. Any ideas how to proceed? thanks in advance.
