Nope, perspective is entirely dependent on subject distance.
If you take a photo with a 35mm lens and from the same point with a 350mm lens
the perspective is identical. You can prove this by taking the two photo
croping and enlarging the same area from the 35mm as in the 350mm lens photo.
They will be identical as to prespective.

Paul,
I made up some thoughts that probably show that you're wrong.
To me, solving this kind of problem by thinking is too hard, so I made a
little sketch (low-fi, I know, but it's late and I wanted to share the
idea) that illustrates why perspective depends on focal length.
The sketch and some explaining words are found at

Let me know what you think about it,

Well, yes, of course. In truth though, I only have one really long
lens -- an A400/5.6 -- so I make do with that. There's no selection
process involved <vbg>.
My only point was that when shooting a given object at a given
percentage of frame fill, the 400 quite obviously delivers a
perspective on APS digital identical to that of a 600 on 35mm film. In
other words, the tests that Shel is going to perform will reveal
exactly that. As you and others have said, the perspective is
dependent on distance from subject (and therefore FOV) rather than
focal length.
