 I use both, the dist.tar.bz2 attachment is what I have in ~/.bin, which is in 
the first entry in $PATH. Given that ccache is almost worthless for anything 
but recompiles after updating CVS (and even then I don't get much higher than 
50% hits), the scripts use ccache only for CVS rebuilds. 'dmake' is 'make' 
using distcc, 'kdecvs' is for CVS rebuilds (I have sources in 
~/build/src/kdelibs etc. and builddir is ~/build/suse/kdelibs etc., the 
script is run from builddir). 'ccache' is simply ccache, picking the right 
ccache repository based on current directory (I use different ccache 
repositories for different CVS modules, so that they don't make each other go 
away from the cache) - I don't call this script directly though. 'kde3' is a 
script setting up $KDEDIR etc. for my working KDE build, you may want to 
remove it from the kdecvs script.

 Note that last time I checked, ccache needed the attached patch in order to 
work with gcc3+.
