label angle follow error

[Travis Kirstine GIS Tech]

Hi
I was looking at the Boston FreeMap and noticed that they using the ANGLE
FOLLOW in the label definition.  We've just updated to mapserver to  4.8.3
and I was hoping to try out ANGLE FOLLOW but I just recieve a error.  Is
there any trick to use FOLLOW?
