What you said in the above paragraph is not strictly correct. To the best of
my knowledge Bacula has no paths hardcoded, and in particular, the path to
the tools in dvd-handler are definitely not hardcoded. They are defined when
Bacula is configured. If the tools do not exist on your system, then there
may be specific defaults. More likely in your case, you already had the
tools in /usr/bin (or perhaps that is where the rpm expects them). When
rebuilding the tools from source, you have the choice of where to put the
binaries, and apparently their default does not agree with what was
previously the case (when you built Bacula or when the rpms were built).

This is a good point.

Unfortunately, your DVD problems may not be over as the current Bacula support
for DVDs is at best BETA.
