Re: segfault with rotate() using visual 5.4 on Debian i386

When I run your program on Windows I get this:

Traceback (most recent call last):
  File "Untitled", line 4
    b.rotate(pi/4)
ValueError: primitive.rotate(): angle of rotation must be specified.

The rotate statement should look like this  b.rotate(angle=pi/4)

The C++ code at wrap_primitive.cpp, line 48, is this:

throw std::invalid_argument(
            "primitive.rotate(): angle of rotation must be specified.");

I don't know why Debian would segfault rather than giving an error.
However, I note that translate_exception shows up in your error
report, and in INSTALL.txt there is the following comment (though if
this were the problem I would expect the compilation to fail):

If you get this error in compiling cvisualmodule.cpp:
		
    In file included from /usr/include/boost/python/exception_translator.hpp:12,
    from ../../vpython-core2/src/python/cvisualmodule.cpp:12:
    /usr/include/boost/python/detail/translate_exception.hpp:34:
	      error: expected nested-name-specifier before "add_reference"

	You need to make this change:
	
	In /usr/include (probably), change /boost/python/detail/translate_exception.hpp
