To add on -- the command appears to just be using yacc, not
$AMBERHOME/bin/yacc. I'm tempted to suggest that maybe the system you're
testing the build on doesn't have a system yacc installed.
I'm also pretty sure that the system yacc (or bison) will be used before
the Amber yacc if it's present. I say this due to a thread which I think I
started on the dev list a couple years ago regarding the fact that the
Amber yacc didn't even work for what Amber needed it to do -- it had just
been masked for so long since it was never really needed.
Scott B. had found the offending line and fixed it. Here is one of the
threads: http://dev-archive.ambermd.org/201107/0023.html -- it can be
traced through there. I've built parallel without serial first plenty of
times, and it's never broken for me. Presumably because a system yacc
filled the dependency that your automated build system is choking on.
I agree that yacc should probably be a parallel build dependency, but if
it's already installed on the system (which is typical) I don't think it
matters.
All the best,
Jason
