It's not that I want to be able to use arial, it's that I'm getting the above message just by trying to make a simple plot with PNG terminal.  If I use pngcairo, then there is no error message.   If you notice, the first script I posted says nothing about fonts at all. Yet it gives the "cannot find arial" message.  
What is the source of the error?
