Here's a lesson:  if all else fails, cruise around Bugzilla for a while 
& you might figure out what the problem is.  For anyone interested, the 
resolution is in bug #495.  It turns out my class definition in the map 
file needed a style section (even if it is empty).  Once I added that, 
things started falling into place.  Here's a working example for 
anybody's future reference:

---------------------------------

$layer = $map->getLayerByName('line_layer');
$layer->{status} = 1;
my $linePoint1 = new mapscript::pointObj();
$linePoint1->{x} = 272048; $linePoint1->{y} = 199772;
my $linePoint2 = new mapscript::pointObj();
$linePoint2->{x} = 272450; $linePoint2->{y} = 200074;
my $line = new mapscript::lineObj();
$line->add($linePoint1);
$line->add($linePoint2);
my $shape = new mapscript::shapeObj($mapscript::MS_SHAPE_LINE);
$shape->add($line);
$shape->{text} = "LINE TEXT";
$shape->draw($map, $layer, $img);

----------------------------------

LAYER
   NAME "line_layer"
   STATUS ON
   PROJECTION
     "init=epsg:26958"
   END
   TYPE LINE
   CLASS
     STYLE
     END
     LABEL
       ANGLE AUTO
       FONT arial
       TYPE TRUETYPE
       POSITION UC
       SIZE 7
       COLOR 0 0 0
     END
     COLOR 0 0 0
     SIZE 10
   END
END
