Oh, sorry: my cut & paste mistake. Substitute "conftest_wrap.cxx" for
"conftest.i" in the C++ compiler command! That file is generated from
conftest.i by SWIG: the output should be valid C++, but the input is not ;)

You'll find the prototype for this suggestion in the Rivet configure.ac
file, which defines the tests that are failing for you.

Good luck,
Andy
