Yep, I'm not against it.
But I think I should clarify why I've added support for LAPACK. First,
the warning was quite anoying, but it's not most important, it just
made me think about adding LAPACK.

I've experimentally linked hugin with LAPACK and tried it on several
panoramas. The results were the same (or almost the same). But I've
one nice* testing panorama which suffers a lot from unstability of
these methods. The vignetting optimization returns usually range from
-40 to 40 for all values (results should be around 0). But in about
25% of all tries it returns the values around -40 or 40 (which is
quite bad). After linking it with LAPACK the number of such strange
values lovered and the worst results were usually about -20 or 20 (but
still bad). But it could be luck.

* nice more in meaning good for testing than anything else
