compiling inventor on 64-bit Suse 10 Linux: red bias

Dear all, 

I have compiled inventor on Suse 10 64-bit Linux, and there seems to be an odd red bias in what I am seeing. I have modified the example 05.2.IndexedFaceSet.c++ , as enclosed below... and I am seeing a red stellated dodecahedron, even with no color specified at all. If I try to specify a blue, I get a magenta, and so on. 

I compiled with -fPIC. Can anyone suggest a course of action. 

#if 0 
// Colors for the 12 faces
static float colors[12][3] =
{
   {1.0, .0, 0}, { .0,  .0, 1.0}, {0, .7,  .7}, { .0, 1.0,  0},
   { .7, .7, 0}, { .7,  .0,  .7}, {0, .0, 1.0}, { .7,  .0, .7},
   { .7, .7, 0}, { .0, 1.0,  .0}, {0, .7,  .7}, {1.0,  .0,  0}
};
#else
// Colors for the 12 faces
static float colors[12][3] =
{
   { 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0},
   { 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0},
   { 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0},{ 0.0, 0.0,  0.0}
};
#endif

   SoSeparator *result = new SoSeparator;

   SbVec3f  pos1= SbVec3f(0,0,3); 
   SbVec3f  pos2= SbVec3f(0,0,-3); 
   SbVec3f  colorWhite=  SbVec3f(1,1,1);

   light1->location.setValue(pos1);
   light1->color.setValue(colorWhite);
   light2->location.setValue(pos2);
   light2->color.setValue(colorWhite);
   result->addChild(light1);               
   result->addChild(light2);               

   // Define colors for the faces
   SoMaterial *myMaterials = new SoMaterial;
   myMaterials->diffuseColor.setValues(0, 12, colors);
   result->addChild(myMaterials);
   SoMaterialBinding *myMaterialBinding = new SoMaterialBinding;
   myMaterialBinding->value = SoMaterialBinding::PER_FACE;
   result->addChild(myMaterialBinding);

   // Define coordinates for vertices
   SoCoordinate3 *myCoords = new SoCoordinate3;
   myCoords->point.setValues(0, 12, vertexPositions);
   result->addChild(myCoords);

   // Define the IndexedFaceSet, with indices into
   // the vertices:
   SoIndexedFaceSet *myFaceSet = new SoIndexedFaceSet;
   myFaceSet->coordIndex.setValues(0, 72, indices);
   result->addChild(myFaceSet);

   result->unrefNoDelete();
   return result;
}

I am a novice with inventor. 

Thanks for your kind assistance.
