Thanks!  That did it!

%screen -v
Screen version 4.09.01 (GNU) 20-Aug-23

What was the issue?  If I understand it, it seems the GNU screen from
the pkg-collection was compiled against a libc.so.7 with a certain
internal version named FBSD_1.8 while my system had a libc.so.7 with an
internal version lower than FBSD_1.8.  A now-and-then comparison:

(*) Now

%strings /lib/libc.so.7 | grep FBSD
FBSD_1.0
FBSD_1.1
FBSD_1.2
FBSD_1.3
FBSD_1.4
FBSD_1.5
FBSD_1.6
FBSD_1.7
FBSD_1.8
FBSDprivate_1.0

%which screen
/usr/local/bin/screen
%strings /usr/local/bin/screen | grep FBSD
FBSD_1.0
FBSD_1.3
FBSD_1.5
FBSD_1.7
FBSD_1.8
%

(*) Then

%strings /usr/local/bin/screen | grep FBSD
FBSD_1.0
FBSD_1.3
FBSD_1.5
FBSD_1.7
FBSD_1.8

%strings /lib/libc.so.7 | grep FBSD
FBSD_1.0
FBSD_1.1
FBSD_1.2
FBSD_1.3
FBSD_1.4
FBSD_1.5
FBSD_1.6
FBSD_1.7
FBSDprivate_1.0

That suggests that screen evolved a bit quicker than the ``base system''
(if that's the right name).

I appreciate the help and any more info anyone might provide.  Thanks!
