You can enable this module by creating a symbolic
link from ${PREFIX-php}/conf/php5.sample/mapscript.ini to
${PREFIX-php}/conf/php5/mapscript.ini.

#ln -fs ${PREFIX-php}/conf/php5.sample/mapscript.ini \
	${PREFIX-php}/conf/php5/mapscript.ini

If you plan to use PHP mapscript extension with a chrooted httpd, make
sure to copy the libs needed by mapscript.so file binary from ${LOCALBASE}/lib,
but also the projection definitions from libgeotiff and proj packages to the
chroot:

# mkdir -p ${PREFIX-php}/${LOCALBASE}/share/{epsg_csv,proj}
# cp ${LOCALBASE}/share/epsg_csv/* ${PREFIX-php}/${LOCALBASE}/share/epsg_csv
# cp ${LOCALBASE}/share/proj/* ${PREFIX-php}/${LOCALBASE}/share/proj
