Don't know. I just removed all obj, and started a fresh build.

Looks like my previous build (MKUPDATE=YES) has made some mistakes by
linking with 2 libcrypto versions at the same time ...

njoly@lanfeust [NetBSD/src]> ldd /usr/bin/ssh
/usr/bin/ssh:
        -lgssapi.5 => /usr/lib/libgssapi.so.5
        -lcrypt.0 => /usr/lib/libcrypt.so.0
        -lcrypto.2 => /usr/lib/libcrypto.so.2
        -lasn1.6 => /usr/lib/libasn1.so.6
        -lcom_err.4 => /usr/lib/libcom_err.so.4
        -lroken.12 => /usr/lib/libroken.so.12
        -lkrb5.20 => /usr/lib/libkrb5.so.20
        -lkafs.6 => /usr/lib/libkafs.so.6
        -ldes.7 => /usr/lib/libdes.so.7
        -lkrb.6 => /usr/lib/libkrb.so.6
        -lz.0 => /usr/lib/libz.so.0
        -lssh.2 => /usr/lib/libssh.so.2
        -lcrypto.3 => /usr/lib/libcrypto.so.3
        -lc.12 => /usr/lib/libc.so.12

njoly@lanfeust [NetBSD/src]> ll /lib/libcrypto*

Will wait until it finish and report.
