[TYPO3] using gmenu lately

[David Banning]

I have not used GMENU since version 3.6 or earlier. I have not seen a
lot of use or examples lately either. I attempted a code snippet
that I found on typo3wizard.com (below). It renders the apache2 error;

PHP Fatal error:  Call to undefined function  imagettfbbox() in /usr/hosting/sky/typo3_src-4.1.5/t3lib/class.t3lib_stdgraphic.php on line 970, referer: http://sky.3s1.com/typo3/alt_db_navframe.php?

I am using php5.2.5 and typo3 4.1.5

Any points would helpful.

temp.gmenu = HMENU
temp.gmenu.1 = GMENU
temp.gmenu.1 {
  NO {
    wrap = <div>|</div>
    XY =100,32
    5 = IMAGE
    5.file = fileadmin/samples/button.gif
    10 = TEXT
    10.niceText=1
    10.text.field = title
    10.fontFile = fileadmin/fonts/Agent_Orange.ttf
    10.offset=6,20
  }
   
  RO < .NO - ERROR: Line 39: Object copied in this line "RO < .NO" would leave either the value or properties untouched in TypoScript Version 1. Please check that this is not a problem for you.
  RO = 1
  RO.10.fontColor = #FFFFFF
  RO.5.file = fileadmin/samples/button_act.gif
}
