Hi Paul.  I'm running Gentoo, PHP 4.3.9, GD 2.0.26, FreeType 2.1.5-r1.  
You can see my phpinfo at 
http://fisher.cnr.berkeley.edu/~kueda/phpinfo_mapscript.phtml.  <nudge> 
didn't work but <textbuttonnudge> did.  Thanks for alerting me to the 
existence of such a tag.   The app is at 
http://fisher.cnr.berkeley.edu/vtm/data/mapbrowse/.  It's still a work 
in progress, so don't be surprised if there are a few formatting 
problems.  I set the textbuttonnudge back to 0 so you can see what it's
