It was never broken, it's been a transient problem in pkg_add.
If you experience the problem, it's your fault. The ports tree
is tracking 2.7, the problem does not exist in 2.7.
Install screenrc in /etc (but do not overright existing file).
Install latest screenrc and screencap in /usr/local/lib/screen for
reference (and so pkg_add knows where to get them from).
