[OS X TeX] Snow Leopard font problems

[Stephen Anderson]

I haven't been following this list closely lately, so something  
similar may already have been discussed.  If so, I'm sorry for the  
duplication, and will be grateful for a pointer to information that I  
should have seen.

Since "upgrading" to Snow Leopard, I find that anything calling for  
courier fonts (maybe others - this is what I've noticed) shows up in  
the output as empty space.  That is, invoking the url package and  
putting \usr{foo at bar.com} in a document results in a long blank space  
in the pdf at that point.  Likewise \texttt{foo at bar.com}.

I'm using the TexLive 2008 distribution, and everything was fine  
before moving from Leopard to SnowLeopard.  In fact, in files that  
were processed in the past, the courier stuff shows up fine in the old  
pdf, but when I rerun LaTeX/XeTeX on the file, it disappears.

I don't have any idea where this problem resides: something similar  
happened to me in a Micr$oft Word document when I set some text to  
"courier std" instead of plain "courier".  But it's in what I do in  
LaTeX that I really care....

Thanks for any help,
