texlive cm-lgc problem?

[Neal Becker <ndbecker2 gmail com>]

Tried processing one of my old lyx files, got this:

pplatex: Process input file 1lyxpreview.dvi
pplatex: Copy data to 1lyxpreview.dvi
kpathsea: Running mktexpk --mfmode cx --bdpi 300 --mag 1+216/300 --dpi 516 fcmr8r
mktexpk: don't know how to create bitmap font for fcmr8r.
kpathsea: Appending font creation commands to missfont.log.
dvipng warning: font fcmr8r at 516 dpi not found, characters will be left blank kpathsea: Running mktexpk --mfmode cx --bdpi 300 --mag 1+113/300 --dpi 413 fctr8r
mktexpk: don't know how to create bitmap font for fctr8r.
dvipng warning: font fctr8r at 413 dpi not found, characters will be left blank

There seems to be cm-lgc in /usr/share/texmf, any ideas what's wrong?
