lilypond try to generate fonts already generated

[Alexandre et/ou Sophie Beneteau]

Hi,

Since a couple of versions of lilypond, I've noticed that the output 
report font generation for already maded fonts...
It slow down the compilation process and did not happend with previous 
versions of lilypond (don't remember exactly... sorry :-( )
I figured it's a lilypond problem since I didn't update my LaTeX 
distribution (TeTeX) nor my kpathsea lib for a long time...
Is it, or my mistake ?

See part from an typical output : (lilypond 1.5.15)
(I'll try 1.5.18 today :-) )

[...]
writing header field `poet' to `orchestre.poet'...
kpathsea: Running mktextfm  cmr8
mktextfm: /usr/local/teTeX/share/texmf/fonts/tfm/public/cm/cmr8.tfm 
already exists.
[...]

Thanks in advance, and please excuse if this problem is my fact (but 
don't know how).

                Alex.
