xmobar 0.11.1

[Nick]

This .xmobarrc

   Config {
      font = "xft:Sans-8:bold",
      bgColor = "black",
      fgColor = "grey",
      position = Top,
      lowerOnStart = False,
      commands = [
         Run Cpu ["-L","3","-H","50","--normal","green","--high","red"] 10,
         Run Date "%Y-%m-%d %a %H:%M:%S" "date" 10,
         Run StdinReader
      ],
      sepChar = "%",
      alignSep = "}{",
      template = "%cpu% } %StdinReader% { <fc=#ee9a00>%date%</fc> "
   }

works on Debian 'squeeze' but on OpenBSD 4.8 i386 produces

   xmobar: /home/nick/.xmobarrc: configuration file contains errors at:
   "Config" (line 11, column 6):
   error reading the commands: this usually means that a command could
   not be parsed.
   The error could be located at the begining of the command which
   follows the offending one. field: [
         Run Cpu ["-L","3","-H","50","--normal","green","--high","red"] 10,
         Run Date "%Y-%m-%d %a %H:%M:%S" "date" 10,
         Run StdinReader]

It does work if I remove use of the 'Cpu' plugin.  Help?
