Labels DO NOT appear on ms_newPointObj()?

[Eric Bridger]

If $map->drawLabelCache() is returning an error you should check the mapserver error log.

You should not need a LABELITEM, you are providing the text. I would also try removing the LABELMAXSCALE, LABELMINSCALE items
and try setting FORCE TRUE in you LABEL.
