[XeTeX] Suddenly fonts are not found

[Jon Breitenbucher]

Hello all. I hope someone can give me an idea of what may be  
happening. I have documents that I typeset less than a month ago with  
XeTeX and yesterday when I opened the PDF output all the math  
characters are being shown with Helvetica as a substitute. They were  
fine when I viewed and printed them last month. Now when I typeset  
them I get things like

*** font activation failed (status=0): lmsy8.pfb

*** font lmsy8 (LMMathSymbols8-Italic: file 'lmsy8.pfb') not found

sudo texhash does not fix it and the LM fonts are available to the  
system. Typesetting with just PDFLaTeX works fine. I'm stumped. Thanks.
