Actually, I've upgraded ccache to _2 and it doesn't say anymore what to put in 
make.conf.  Is it still :

.if ${.CURDIR:M/usr/src*} || ${.CURDIR:M/usr/obj*}
CC=cc
CXX=c++
.else
.if defined(NOCCACHE)
CC=/usr/bin/cc
CXX=/usr/bin/c++
.else
CC=cc
CXX=c++
.endif
.endif

or is it :
#.if !defined(NOCCACHE)
#.if ${.CURDIR:M/usr/src*}
#CC=/usr/local/libexec/ccache/cc
#CXX=/usr/local/libexec/ccache/c++
#.else
#CC=cc
#CXX=c++
#.endif
#.else
#CC=/usr/bin/cc
#CXX=/usr/bin/c++
#.endif

and do I still have to setenv CCACHE_NOHASH_SIZE_MTIME yes for a 
buildworld/kernel?

Thanks,
Nicolas.
