[Fedora TeX Live] xelatex troubles

[Adrian Reber]

I had texlive 2011 installed on Fedora 16 and right now updated to 2012
because I had (and still have) following problem with xelatex:

xelatex abstract.tex
This is XeTeX, Version 3.1415926-2.3-0.9997.6 (TeX Live 2012/dev)
 restricted \write18 enabled.

kpathsea: Running mktexfmt xelatex.fmt
I can't find the format file `xelatex.fmt'!


Is this a known problem? Am I doing something wrong?
