kpsewhich unable to find fmtutil.cnf

Hello,
here is my question (I'm a complete newbye, but I didn't find any answer in 
the archive):
Is it normal that the command "kpsewhich fmtutil.cnf" doesn't give any answer 
(whereas kpsewhich texmf.cnf responds /usr/share/texmf/web2c/texmf.cnf)?

I have recently reinstalled tetex on my computer (under debian testing). The 
tetex installation seems to be ok (tested on a simple latex file). But the 
local installation (with a make command) of a shareware package related to 
tetex (this package isFrenchpro, which aims at providing a good french style 
for latex) complains about this file fmtutil.cnf not found. In fact 
fmtutil.cnf exists, but it is located in /var/lib/texmf/web2c/
Thank's for any help.
    F.B.
