Bug 43371

The misc/amanda-server port will not build on a 4.7-RC server with a recent ports collection.  The build fails in the 'changer-src' directory:

Fix: 

The problem seems to occur when both scsi-bsd.o and scsi-cam.o are linked in to chg-scsi.  I don't know enough about the system to know which should be included.
How-To-Repeat: cd /usr/ports/misc/amanda-server; make
