Do: apt-get install lib32ncursesw5 as root.
If there are any more libraries missing, search them here:
http://www.debian.org/distrib/packages#search_contents
(eg. to find the one above which you were missing, you would have to type libncursesw.so.5 in the search field)
When there are several possible matches, choose ones with lib32 in their names. Once you found the right package, install it like in the above example.
