# While extra Python modules are generaly installed in the Python
# interpreter's "site-packages" directory, Debian prefers using the
# "dist-packages" nomenclature. This macro uses the interpreter
# designated by the PYTHON variable to check the interpreter's PATH
# and sets the PYTHON_MODULES_PATH by taking the prefix into account.
