Dolfin has no dependencies to syfi, that can't possibly be a problem.
If I make a library that happens to fit the interfaces in your software,
you can't be legally bound by what I did...

Clearly, SyFi must be GPL, and I guess swiginac as well.
Since sfc uses swiginac and SyFi from python, does it have
to be GPL as well?
