I don't understand what's happening here and I would appreciate a
presentation of how computers and FreeBSD work that makes this happen.
In particular, I see (via ldd below) that the library libc.so.7 is to be
found by the linker, but perhaps the loader expected a different one and
is upset it didn't find it?

# screen
ld-elf.so.1: /lib/libc.so.7: version FBSD_1.8 required by /usr/local/bin/screen not found

# ldd $(which screen)
/usr/local/bin/screen:
libncursesw.so.9 => /lib/libncursesw.so.9 (0x2491b92b1000)
libtinfow.so.9 => /lib/libtinfow.so.9 (0x2491b7dff000)
libutil.so.9 => /lib/libutil.so.9 (0x2491b84c2000)
libulog.so.0 => /lib/libulog.so.0 (0x2491b9f04000)
libcrypt.so.5 => /lib/libcrypt.so.5 (0x2491ba31d000)
libc.so.7 => /lib/libc.so.7 (0x2491ba6aa000)
libmd.so.6 => /lib/libmd.so.6 (0x2491bb457000)
[vdso] (0x2491b7ce3000)

I first installed screen50-5.0.0 with /pkg install/. Seeing the
problem, I tried to install /screen49-4.9.1_5/, which I did:

# pkg which /usr/local/bin/screen
/usr/local/bin/screen was installed by package screen-4.9.1_5

--8<-------------------------------------------------------->8--- screen49-4.9.1_5 Multi-screen window manager
screen50-5.0.0 Multi-screen window manager --8<-------------------------------------------------------->8---

Both versions display the same problem.

This is a FreeBSD 14.

Does updating to FreeBSD 14.0-RELEASE-p11 resolve the libc.so.7 version mismatch? <URL:https://www.freebsd.org/security/advisories/FreeBSD-SA-24:16.libnv.asc>

Try building screen from ports. It may self adjust to your version of
libc.

Packages from the FreeBSD pkg mirror are likely now being
linked against FreeBSD 14.1 libc.so.
I hear echoes of the Wolfgang's bug report in this FreeBSD forum post: <URL:https://forums.freebsd.org/threads/lib-libc-so-7-version-fbsd_1-7-not-found.88663/>

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!

FreeBSD 14.0 is EOL.
<URL:https://www.freebsd.org/security/unsupported/>

Presumably FreeBSD.ORG's pkg build servers are now at 14.1 with the
newer libc.so.

You might want to upgrade: <URL:https://www.freebsd.org/releases/14.1R/installation/#upgrade>
