I have seen that kind of failure when the port was built on a system
that had www/libwww installed. In that case libmd5.so from libwww is
linked to samba in preference of the system's libmd.so.
I sent a note to the port's maintainer, a few weeks ago, but apparently
he did not apply the patch I included, which fixes the port.
In case you have libwww installed, you can simply temporarily deinstall
it while you build samba42.
Or apply the attached patch (copy it to the samba42 port's files
directory and rebuild the port).
Best regards, STefan
