[poppler] Helvetica fonts not embedded, displays junk

[Rod Butcher]

Greetings from Sydney. I'm using evince/poppler to display a document 
from IBM which displays junk, and in properties/fonts lists helvetica 
not embedded. Debug output displays :_
Error: Couldn't find a font for 'Helvetica'
some font thing failed
Error: Couldn't find a font for 'Helvetica Bold'
some font thing failed
Error: Couldn't find a font for 'Helvetica Oblique'
some font thing failed

I compiled poppler & evince myself from cvs HEAD, couldn't find any 
configure options about fonts. Is theere something I need to learn about 
fonts to build / run poppler correctly ? Where does it get fonts from if 
they're not embedded ?
thanks
Rod
