But one can also augment the default search path with:

    AUXLIBS="-Wl,-R,/some/path ..."

When I build Postfix for my FreeBSD server, I use:

    make -f Makefile.init dynamicmaps=yes shared=yes pie=yes \
        'CCARGS=-DDEF_MAIL_OWNER=\"postfix\" -DDEF_SGID_GROUP=\"maildrop\" 
-DHAS_EAI -DUSE_SASL_AUTH -I/usr/local/include -DHAS_PCRE -DUSE_CYRUS_SASL 
-I/usr/local/include/sasl -DUSE_TLS -I/usr/local/include/db5 -DHAS_CDB 
-DHAS_LMDB' \
        'AUXLIBS=-L/usr/local/lib -lsasl2 -lpam -lcrypt 
-Wl,-rpath,/usr/local/lib -fstack-protector-strong  -lssl -lcrypto 
-L/usr/local/lib/db5 -ldb-5.3' \
        'AUXLIBS_CDB=-L/usr/local/lib -Wl,-R,/usr/local/lib -lcdb' \
        'AUXLIBS_PCRE=-L/usr/local/lib -Wl,-R/usr/local/lib -lpcre' \
        'AUXLIBS_LMDB=-L/usr/local/lib -Wl,-R/usr/local/lib -llmdb' \
        command_directory=/usr/local/sbin \
        config_directory=/usr/local/etc/postfix \
        daemon_directory=/usr/local/libexec/postfix \
        data_directory=/var/db/postfix \
        mailq_path=/usr/local/bin/mailq \           
        newaliases_path=/usr/local/bin/newaliases \ 
        queue_directory=/var/spool/postfix \        
        sendmail_path=/usr/local/sbin/sendmail \    
        shlib_directory=/usr/local/lib/postfix \    
        html_directory=/usr/local/share/doc/postfix \
        manpage_directory=/usr/local/man \
        readme_directory=/usr/local/share/doc/postfix \
        makefiles

I don't need ".../db5" in the runpath for db-5.3, because the
version-explicit SONAME library is also installed into /usr/local/lib.
Only the bare .so and .a files require /usr/local/lib/db5.  So I use
"/usr/local/lib" instead.
