dont set your CC like that
After the installation of the base systems I immediately installed ccache and used it since that time without any problem until now - and in the meantime there are ~ 3000 files in /var/log/portage. That's why IMHO it is not unlikely that the problem is related rather to the ebuild of the specific package than to the system configuration (which is very straight forward). Sorry, but your answer is not very helpful and don't give any hint what's wrong and/or how this problem can be avoided. BTW setting CC to 'ccache gcc' can be read at http://ccache.samba.org/ . Reopend for a - possible - solution.
the entire point of FEATURES=ccache is so that you dont screw around with CC
Ok, but would be nice if this behaviour is included in the doc, because portage is not the main cause for the existance of the user root. If portage cannot handle correctly this environment variable - which is used by the user root for a lot of different things - then either portage should unset CC in its sandbox or - as I said before - this is a point for the doc, isn't it ?
Here is a 2nd example where this CC settings produces trouble: bug #94255
