I do not know how MacOX works, but do you have permissions to write on /usr/texbin as a user? If not, you would have to run

sudo luatools --selfupdate

and then proceed.

Many thanks for your answer: in fact I tried once with "sudo luatools --selfupdate", but the answer is:

LuaTools | error unable to identify cnf file
LuaTools | error unable to identify cnf file
LuaTools | no cnf files found (TEXMFCNF may not be set/known)
LuaTools | to be replaced old script /usr/texbin/luatools
LuaTools | unable to locate new script
LuaTools |
LuaTools | runtime: 0.002 seconds

Nevertheless, I have already issued the command

export TEXMFCNF="/usr/local/texlive/2008/texmf/web2c/"

Can it be that I have to add other paths to TEXMFCNF? In this case how one can find all these paths to add? Has something changed recently in the ways TEXMFCNF has to be set?

Thanks again: OK
