[OS X TeX] missing symbols in mathptmx with pdftex

[Nathan Sanders]

Thanks for the reply (and also to Richard Koch for his off-list  
reply).  I just updated Acrobat Reader to 8.1.1 and tried the same  
PDF, and the summation symbol is still missing!  I've uploaded it to  
the following URL:

	http://wso.williams.edu/~nsanders/missing-summation.pdf

I'm beginning to think there is something broken in our TeX  
distributions, since it seems to be happening only to us (and I did  
the installation on both our computers).  I find it bizarre, however,  
that the symbol is missing in Acrobat, but not in Skim or Preview.  (I  
don't find it bizarre that pdftex is doing something different than TeX 
+Ghostscript, of course!)

The following is the console output that generates the bad PDF.  I  
don't see anything unusual myself, but maybe someone more knowledge  
can spot a problem:
