php56-bcmath-5.6.40: copying /usr/pkg/share/examples/php/bcmath.ini to /usr/pkg/etc/php.d/bcmath.ini

By default, example module configuration file was copied to following
location, and module should be auto-loaded:
/usr/pkg/etc/php.d/bcmath.ini

If you use custom /usr/pkg/etc/php.ini, or nonstandard module
configuration file location, you might need to add explicit load directive:
extension=bcmath.so
