No, "/usr/bin/swig2.0 -version" gives me:

$ /usr/bin/swig2.0 -version

SWIG Version 2.0.1

Compiled with g++ [i686-pc-linux-gnu]

Configured options: +pcre

Please see http://www.swig.org for reporting bugs and further information

Yes, I think so too. I tried it but when I run demo_poisson.py I still
get this error:

Traceback (most recent call last):
  File "demo_poisson.py", line 26, in <module>
    V = FunctionSpace(mesh, "Lagrange", 1)

    """%cpp.__swigversion__
OSError: PyDOLFIN was not compiled with the present version of swig.

It seems that "check_and_set_swig_binary" in instant/config.py never
gets called.
