Ok, so after a little additional research, it looks like one can use the 
mapscript generateSLD() function to convert mapfile layer definitions to 
SLD.

BUT! only 16 of 32 layers generated useful SLD files using perl mapscript;

Anyone tried this on 6.2?  Is this a bug?
Any ideas how to work around this isue?

Details follow:

MapServer version 6.2.0-beta1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG 
SUPPORTS=PROJ SUPPORTS=GD SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO 
SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT 
SUPPORTS=WFS_SERVER SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR 
INPUT=GDAL INPUT=SHAPEFILE

Here is my perl script:

woodbri at mappy:~/work/geoserver$ cat mapfile2sld
#!/usr/bin/perl -w
use strict;
use mapscript;

sub Usage {
     die "Usage: mapfile2sld mapfile out_dir\n";
}

my $mf  = shift @ARGV || Usage();
my $dir = shift @ARGV || Usage();

mkdir $dir, 0777;
die "Directory '$dir' does not exist or failed to create it! : $!\n"
     unless -d $dir;

my $oMap = new mapscript::mapObj( $mf );

for (my $i=0; $i<$oMap->{numlayers}; $i++) {

     my $oLay = $oMap->getLayer($i);

     my $SLD = $oLay->generateSLD();

     my $fname = "$dir/" . $oLay->{name} . ".xml";
     open(OUT, ">$fname") || die "Failed to create '$fname'! : $!\n";
     print OUT $SLD;
     close(OUT);
}

16 of the files contain nothing more than this:

woodbri at mappy:~/work/geoserver/tiger2011-mc$ cat linear_water.xml
