EDIT: solved. I needed the texlive-fontsextra package.
When I try to export my lyx document to pdf (pdflatex), I get the following message:
File does not exist:
So I went into that directory and looked at Draft_mk_2.log:
!pdfTeX error: pdflatex (file cm-super-t1.enc): cannot open encoding file for reading
==> Fatal error occurred, no output PDF file produced!
I uninstalled and reinstalled lyx, made sure I had the latest version (1.5.5-1), made sure I had t1lib and t1 utils, etc. But locate still doesn't find the missing file on my system.
Any help would be greatly appreciated.
