When I looked at levmar a few years ago I had the distinct impression that its 
authors really wanted it to be statically linked. The result of that is the 
multitude of different (patched) versions of levmar that you see embedded in 
different projects. There's a lot of work to do to convince the upstreams of 
freemat, hugin, meshlab, sextractor, starlink-ast, stimfit and teem that they 
want to work with a non-patched and up-to-date levmar instead of just 
continuing with their own versions.

Levmar upstream does have some support for building a shared object but I 
didn't feel confident that sovers would be properly managed and I didn't want 
to take on that responsibility myself which is why I abandoned my previous 
efforts with levmar too.

(just an added data point for anyone thinking of taking up packaging levmar)
