Well, the stretching /is/ right. You can't map the view of a 3d world,
as seen from a particular point, onto a 2d plane without distorting
/something/.
You would see the same effects in the real world with a pinhole camera,
which is the camera type after which POV-Ray's default camera is
modeled. Wide-angle lenses for cameras are sometimes(?) designed to
somewhat compensate for such effects, but at the cost of distorting the
image in some other way, e.g. distorting straight lines (fisheye lenses
are an extreme example of this).
That said, the ultra_wide_angle camera type might give you what you want.
To avoid any distortions at all, you'll need to move the camera as far
away from the scene as possible and reduce the camera angle (in that
case it's pretty irrelevant whether you choose the default camera or the
ultra_wide_angle camera - or go for the orthographic camera right away.
