[postgis-users] shp2img OK, mapserver not OK

Hello Listers:
I've built postgresql, postgis, and mapserver (with postgis support).
I can load a shapefile into postgis and everything looks good. I know
my mapserver install works because I can display shapefiles with it.
But when I try to use a postgis connection as the data source, I get a
white box. When I run shp2img with the same map file, it gives no
errors and successfully returns an image of data that came out of
postgis. So, ultimately, the problem is that mapserver won't return an
image from a postgis source whereas shp2img will return an image from
the same mapfile. When running the mapfile through mapserver, the log
file indicates that it completes normally, but no image. I can add a
second layer to this same mapfile that accesses a shapefile and that
shapefile is returned by mapserver, but not the layer whose source is
postgis. Any ideas on how to troubleshoot this? I'm somewhat of a
newbie to this, so apologies if this is something I should
know...thanks in advance...
environment:
postgreSQL 7.3
postgis 0.7.3 (from CVS about a week ago)
