does "algebra/solver/solver.mac" broken?



I tried the "test.mac" from the new solver package for maxima but it fails.
Is it broken?
(C1) load("algebra/solver/solver.mac");

(D1)        /usr/share/maxima/5.9.1/share/algebra/solver/solver.mac
(C2) block([s:solver([x+y+x^2=a,x-y=b],[x,y],[a,b])],print(s));

MACSYMA was unable to evaluate the predicate:
ERREXP1
#0: SetupSolver(equations=[y+x^2+x = a,x-y = b],solverparams=[[x,y],[a,b]])
#1: SOLVER(equations=[y+x^2+x = a,x-y = b],solverparams=[[x,y],[a,b]])
(solver.mac line 451)
 -- an error.  Quitting.  To debug this try DEBUGMODE(TRUE);)

Also,
To start the "solver mac" correctly the  call paths inside the package
should be replaced to "algebra/solver" instead ./
