Using ccache and clang in FreeBSD 10

Z

I would like to recompile FreeBSD 10 without debuggings and other optimizations. For faster compilation, I would like to use ccache with clang (which is reportedly default in FreeBSD).

What could be an ideal way*** to recompile FreeBSD 10 using clang and ccache? Any input with some successful configurations will be appreciated!

Thanks!



*** I followed some howtos from this forum without success (maybe they are inapplicable to FreeBSD 10), viz.
1) [HOWTO] buildworld using clang + ccache
2) HOWTO: FreeBSD with CCACHE
3) BuildingFreeBSDWithClang
 
At present, a buildworld on FreeBSD-10 does not work with devel/ccache enabled. A sort of weak workaround is to leave /usr/obj from previous builds and add the -DNOCLEAN option for buildworld.
