GNU screen libc.so.7 issue

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.
