I have now achieved at least a temporary fix to this problem.  I  
pasted Peter Baker's repaired TeX Gyre Termes fonts into the  
directory where my input file lives; I ran texhash; and I changed the  
fontspec call in the preamble to the following:

\setmainfont[Mapping=tex-text,Ligatures=Common,Numbers=OldStyle] 
{TeXGyreTermes-Regular}

This allows for all the other fonts (italic, bold, etc.) to be found  
too.  I guess this will have to do until I upgrade to 10.5!

Thanks for your help, everyone.
