Not sure, but I think it will few very few. net-im/pebrot is an
IM written in python and it uses ncurses. It works well. Let me
try to figure out how many py- ports actually uses ncurses or
readline, and see if they are broken or not. But as I stated
below, other distribution does the same thing so I suspect
there are few issues.
