OK, adding the -u flag to the #! line doesn't help.

I have also reproduced the error on a Mac G4 PB without CGI.
I used the same ttf from the linux box and also tried a ttf from a  
windows box.
I also tried it with StringIO but it didn't help me at all, but it  
does save me having a tempfile on disk.

Any more ideas?

Maybe Ill try reading through pdfdoc and ttfonts when I have some  
spare time.
