no, it is at

/home/texlive2013/bin/x86_64-linux/luatex

where all other binaries are. This works fine for the old luatex, also 
the PATH is set to this place.

Well, I just replaced the working luatex binary by the one I built. If 
it worked for the the old one, it should be fine for the new one, too, no?

It's called texmf.cnf here, but I guess that was a typo. What exactly 
should I adapt here?
