Hello,

On Mac OS X 10.9.4 (Mavericks), with the following setup:

• perlbrew perl 5.18.1, (compiled with -Dusethreads)
• Expect v1.21
• IO::Tty, v1.10
• IO::Pty, v1.10
• bc, v1.06

I get this output:

1..1
    1..1
bc 1.06

On Ubuntu 12.04, with the following setup:

• Expect v1.21
• IO::Tty, v1.11
• IO::Pty, v1.11
• bc, v1.06.95

I get this output:

So, I upgraded IO::Tty and IO::Pty on my Mac to v1.11 and tried again. I got the same test failure:

bc 1.06
