The latter.

It seems unlikely that it's v2's fault, but static linking is not
supposed to be required.  The easy way to test it is to build the same
test in v1 using dynamic linking:

  run ../test/exec.cpp <dll>../build/boost_python
      : : exec.py : $(PYTHON_PROPERTIES)
      <define>BOOST_PYTHON_STATIC_MODULE ;

(I think)
