I'm not sure how you're seeing that.  On my CentOS 4.4 system, more will 
not list a library file; it exits saying "Not a text file".

I can list some of the text content of a library using strings, but the 
libs I have looked at do not contain the string "INPUT" at all.  That 
is, "strings libmenu.so | grep INPUT" returns no matches.  Is this on 
another variety of *nix?

On my CentOS system, it is:

Does cmp say that the two libraries libmenu.so and libmenuw.so are 
identical?  If so, it's possible that an error was made assembling the 
ncurses build.  Just speculation though.
