I'll give you what little I know.  I'm currently "suffering" through 
installing and configuring Amanda with an Overland Data DLT 15-slot 
autoloader, but I'm using versions 2.4.1p1 and 2.4.2-beta.  The 2.4.1p1 
version is the latest "officially" released version and there are patches 
for it as well.  On the subject of nuplot, that's only needed is you want 
to use the amplot utility that's included with amanda.  If you don't need 
it or want it, then you don't have to install gnuplot or X.

As for the changer, I'm only to the point of using chio (and recently mtx) 
to control it.  Amanda includes some scripts that will use these utilities, 
namely chg-chio, and chg-mtx (read through the docs, 
TAPE.CHANGERS).  Recently, amanda did include a new changer utility called 
chg-scsi.  From what I understand though, you should use the chg-scsi 
version included with 2.4.2 beta.

A few things to note if you're going to use version 2.4.1p1 of Amanda on 
FreeBSD:
1.  You will get an error when running make, something about 
"ces_data".  You need to get the file /changer-src/scsi-chio.c from the 
2.4.2-beta and use it in compiling 2.4.1p1.
2.  If you're going to use chg-scsi instead of chg-chio or chg-mtx, you 
should also use the chg-scsi included with 2.4.2-beta
3.  In order to use amanda properly, you need to have a tapetype 
definition.  You can get a list of those off of the Amanda web page 
(<http://www.cs.columbia.edu/~sdossick/amanda/>) or you can run the 
tapetype utility.  Once again, it's recommended that you build the tapetype 
included with 2.4.2-beta (change into the /tape-src directory and issue the 
command "make tapetype") as it's significantly faster.
