so libtermcap.so.2 is a link to libtermcap.so who is a link to 
libncurses.so...
Here some information on the same problem on poplog:

http://www.poplog.org/talk/comp.lang.pop/2001/msg00018.html
http://www.poplog.org/talk/comp.lang.pop/2001/msg00016.html

So conclusion should be that linux (and since solaris 2.0) application 
have to be recompiled with libncurses instead libtermcap. This is 
perhaps true for other unix OS. This should avoid confusion.
