>Description:
	The Perl module IO::Pty no longer works after upgrading to
	6.4-PRERELEASE.  The machine is following RELENG6 using
	cvsup and was running 6.3 before.  IO::Pty (or rather the
	Perl module Expect) was running fine until the recent
	upgrade.  IO::Pty is included in the distribution of IO::Tty
	and is used by the Perl module Expect.

	Re-installing IO::Tty from ports or from CPAN did not help.

	This also happened on another machine which I upgraded to
	6.4-PRERELEASE today in order to verify the problem.

>How-To-Repeat:
	install from ports devel/p5-IO-Tty and perform this script

	$ perl -e 'use IO::Pty; $x= new IO::Pty;'
	Cannot create a new IO::Tty from fd 4: Bad file descriptor at -e line 1

>Fix:
	No workaround found yet.
