The AX_BOOST_PYTHON macro uses AX_PYTHON internally to find the include directory for the Python headers. I propose to switch to AX_PYTHON_DEVEL. Aside from being the more canonical choice for the job, this has the following crucial advantage:

Unfortunately, AX_PYTHON always reports the first Python interpreter it finds. As far as I know, there is no way to tell AX_PYTHON which Python version to use on systems where both Python2 and Python3 are installed. AX_PYTHON_DEVEL is better in this respect, as it takes the variable PYTHON_VERSION into account (which is set by the macro AM_PATH_PYTHON). As a consequence, a call to "./configure PYTHON=python2" with an autoconf script containing


sets the header and include directories for Python2 but still links to libboost_python3 instead of libboost_python.

This is fixed in the attached patch. Required changes are very minor. I do not see anything that could cause incompatibilities with old code.
