There are significant changes to the linking options.
I've created and installed the binaries. Simple jobs have run successfully.
I am wondering about the previous patches and why we had them.
Of special note:
* https://svnweb.freebsd.org/ports/head/sysutils/bacula-server/files/patch-src_stored_Makefile.in?revision=399938&view=markup
* https://svnweb.freebsd.org/ports/head/sysutils/bacula-server/files/patch-src_tools_Makefile.in?view=markup
I'll bring in Larry Rosen, who worked on those patches. I think the issue relate more to upgrading and building and running.
