Are you sure? When I tried building the package today I got

     Checking package...
     warning: mark_as_command is obsolete and will be removed from a
future version of Octave
     [findsym]
       ***** test
      symbols
      x=sym("x"); y=sym("y"); f=x^2+3*x*y-y^2;
      vars = findsym (f);
      assert(vars, 'x,y');
      vars2 = findsym (f,1);
      assert(vars2, 'x');
     !!!!! test failed
     T& Array<T>::checkelem (4, -1, 2): range error[sym2poly]
     PASSES 2 out of 2 tests
     [symfsolve]
     PASSES 5 out of 5 tests

(The mark_as_command warning is from another package I have installed,
but I keep forgetting which one.) So something fishy is happening,
"!!!!! test failed" yet "PASSES 2 out of 2 tests". Can you reproduce
this? Perhaps this was happening in February so the tests were failing
but being reported as passing?
