Also the final lldb and liblldb.so are linked against:
...
      -ledit.3 => /usr/lib/libedit.so.3
        -lterminfo.2 => /usr/lib/libterminfo.so.2
        -lgnuform.6 => /usr/pkg/lib/libgnuform.so.6
        -lncurses.6 => /usr/pkg/lib/libncurses.so.6
        -lgnupanel.6 => /usr/pkg/lib/libgnupanel.so.6
...
