how to use "maxima --batch" *reliably* ??



This has nothing to do with the build process.  You seem to want to use
Maxima as a subroutine for some larger calculation.

As Fateman pointed out, Maxima was not designed for this use, and is hard to
use this way because

   1) Maxima often asks questions in the middle of a calculation (e.g. Is
x>0?).
   2) Maxima errors are not designed for consumption by other programs.
   3) Some errors are not clean.
   4) Startup time is long.

We're aware of these issues, and would like to fix them, but they are not
fixed yet. You are welcome to work on them with us.
