Hi Branden,

I don't think this is accurate. I believe that if either ghostscript or URW 
fonts are present you will have all fonts for pdfs. So if ghostscript not 
available but URW fonts are then you will still have the default and U 
foundries.

If neither is available you still end up with a working gropdf but only the 
base 14 fonts are available and you can't produce pdfs with embedded fonts. 
This can be seen when Bruno listed the contents of his font/devpdf directory.

So this, and the configure message, imply that ghostscript is required, but 
this is not true. With both font sources missing, it is true that some of the 
pdf documentation in groff may be missing, but only those which use fonts 
other than the base-14.

What is your understanding?

Cheers
