Did you rebuild dialog4ports after:

20210105:
        ncurses installation has been modified to only keep the widechar
        enabled version.  Incremental build is broken for that change, so it
        requires a clean build.

? Even if you did: Unfortunately, they did not make such an UPDATING
note for libraries that use ncurses when they updated those to avoid
the dependency on the now-missing ncurses material:

Bump shared library versions after ncurses bump in 13.
A few shared libraries in the base system link against ncurses.  An
upgrade from a 12.x host to 13 results in ABI breakage for existing
binaries since the newer versions of these libraries link against the
newer ncurses while the binary itself links against the older ncurses.
For example, dialog4ports built on 12.x sometimes crashes on 13 since
it depends on libdialog which links against ncurses internally.

So now there is a /usr.lib/libdialog.so.9 instead and
a correctly built dialog4ports will show it in the
ldd output:

# ldd `which dialog4ports`
/usr/local/bin/dialog4ports:
        libncursesw.so.9 => /lib/libncursesw.so.9 (0x402a1000)
        libm.so.5 => /lib/libm.so.5 (0x4033a000)
        libdialog.so.9 => /usr/lib/libdialog.so.9 (0x403a5000)
        libc.so.7 => /lib/libc.so.7 (0x40408000)

An incorrectly built dialog4ports will show
/usr.lib/libdialog.so.8 instead.
