I think I found the solution now. (Thanks to a message Angus replied to
about a year ago)

...
pfViewMat.set(ogl_matrix);
pfViewMat.transpose(pfViewMat);
pfViewMat.preRot(-90, 1, 0, 0, pfViewMat);
pfViewMat.postRot(pfViewMat, 90, 1, 0, 0);

chan->setViewMat(pfViewMat);
...

That "seems" to work. Can anyone confirm if this is the correct
solution?
