Something may be missing in your layer definition, but without seeing it 
we can't tell.  Here is a modified version of your script that creates 
its own layer, and does display the symbol properly.  You should compare 
your layer definition with what is set in this example.  Also note that 
if you want to draw labels then you may have to either turn the 
labelcache off, or call $map->drawLabelCache() after drawing the pointObj.

<?php

dl('php_mapscript.so');

// Default values and configuration

$map_path = "/Library/WebServer/Documents/maplab/projects/Naturalists/";
$map_file = "naturalists.map";

$map = ms_newMapObj($map_path.$map_file);

$daLayer = ms_newLayerObj($map);
$daLayer->set("type", MS_LAYER_POINT);
$daLayer->set("transform", MS_FALSE);
$daLayer->set("status", MS_ON);
$class = ms_newClassObj($daLayer);
$style = ms_newStyleObj($class);
$style->color->setRGB(255,0,0);
$style->set("symbolname", "circle");
$style->set("size", 10);

$my_point = ms_newpointObj();
$my_point->setXY(217,240);

$image = $map->draw();
$my_point->draw( $map, $daLayer, $image, 0, "Temp Point" );

$image_url=$image->saveWebImage();

?>
