That may be true, but I'd still check if PATH is suitable
IN THE SCRIPT.  There is a PATH= statement in chg-zd-mtx
that resets what you see from the command line.

The message syntax "prog: line: cmd: command not found"
is pretty specific and only (to my knowledge) used for the
stated purpose.  It is not like "no such file or directory"
that may deal with permissions or typos or ...

Also, line 389 is a line from which mtx would be executed.
It is the only place where mtx would be executed and it
is only called to from three other places in the script.
When called, the command name is passed as $MTX.  From the
message this appears to be "mtx" but I think in amanda.h
or config.h you could specify a full pathname and recompile.

Here are some things you could try to test my idea.
First, replace chg-zd-mtx with a copy.

Edit the copy and insert before line 389 a
"which mtx > file_of_your_choosing 2>&1".

You could also add an "echo $PATH > some_file".

Finally, you could try to specify where mtx is located.
Early in the script set MTX to the full path to mtx,
i.e. "MTX=/usr/local/sbin/mtx".  This will override amanda's
builtin definition.
