[XeTeX] Can't get CM to render with XeTeX

[Nicholas Riley]

Hi,

I've just started playing with XeTeX.  I've got it installed, and all 
the samples render (well, I didn't wait for 800 variants of Skia :) 
except for those which use Computer Modern.

With CM-test.tex, I get:

     This is XeTeX, Version 3.14159-2.1-0.7 (Web2C 7.5.2)
     entering extended mode
     (./CM-test.tex [1]
     *** font cmti10 (CMTI10: file 'cmti10') not found
     *** font cmbx10 (CMBX10: file 'cmbx10') not found
     *** font cmsl10 (CMSL10: file 'cmsl10') not found
     *** font cmr10 (CMR10: file 'cmr10') not found
     *** font cmex10 (CMEX10: file 'cmex10') not found
     *** font cmsy7 (CMSY7: file 'cmsy7') not found
     *** font cmmi10 (CMMI10: file 'cmmi10') not found
     *** font cmmi7 (CMMI7: file 'cmmi7') not found
     *** font cmr5 (CMR5: file 'cmr5') not found
     *** font cmr7 (CMR7: file 'cmr7') not found
     *** font cmsy10 (CMSY10: file 'cmsy10') not found  )
     Output written on CM-test.pdf (1 page).
     Transcript written on CM-test.log.

Any idea why the CM fonts aren't being found?  Do I need to convert 
them somehow?  I have no problem if I use pdfTeX instead.
