question about fonts

[Aaron Solochek <aarons-gnome aberrant org>]

I'm running debian unstable, and am having an issue with fonts in gnome. 
 Specifically, I want to use URW Gothic L as my application font, but 
for some reason the Book and the Demi styles of that font render exactly 
the same.

If I goto font preferences->details->go to font folder, I get a listing 
of fonts at location "fonts:///" which only lists URW Gothic L and URW 
Gothic L, Italic.  Where does the fonts:/// URI get built from?  I know 
the Demi version of URW Gothic L exists on the system 
/usr/share/fonts/type1/gsfonts/a010015l.{afm,pfb}, so I don't know why 
its not being detected.

Anyone know how I can fix or at least better debug this?

Thanks.
