Subject: Highline and Termios issues

Hi,

I have question re: Highline. In this code fragment, when running on MacOS/X:

        agree("overwite #{path}? y/<%= color('N', BOLD) %>", true)
{|q| q.default = false}

... The prompt is followed by a newline in irb/ruby. I can't see an
option in the docs to change this behavior. I'm trying to emulate the
question when copying a directory tree like the Rails command or its
generators do.

Some searching led me to think that the Termios gem may help, but if I
try to install it (Ruby 1.9.2-p0), I get this:


termios.c: In function ‘Termios_to_termios’:
termios.c:182: error: ‘struct RArray’ has no member named ‘ptr’

Thanks (Snow Leopard, BTW)
