[Fedora TeX Live] pdflatex doesn't work after upgrade

[Matthew Saltzman]

pdflatex was working before the recent repo upgrade, but now reports

        $ pdflatex BRIJOC2403.tex 
        This is pdfTeX, Version 3.1415926-2.4-1.40.13 (TeX Live 2012)
        restricted \write18 enabled.
        
        kpathsea: Running mktexfmt pdflatex.fmt
        I can't find the format file `pdflatex.fmt'!

And in fact, I don't see any file with that name.
