I did configure with --with-postgis=<path to pg_config> and mapserv -v reports:

MapServer version 4.8.4 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=SVG SUPPORTS=FREETYPE INPUT=EPPL7 INPUT=JPEG INPUT=POSTGIS
INPUT=SHAPEFILE

Would I get a different error if postgis support was actually included
but the layer or the postgis configuration wasn't correct?

Thanks again for the help.
