[gentoo-user] about ccache permission adjusting

[sempsteen]

Hi,
I've changed my CFLAGS settings and merged ccache for future works. Now i'm
updating my system with "emerge -e world". During merge i realize that
ccache is adjusting permissions before and after for all packages, it's
something like this:

>>> media-libs/libsdl-1.2.8-r1 merged.
* Adjusting permissions on ccache in /root/.ccache

>>> clean: No packages selected for removal.

>>> emerge (105 of 405) media-libs/jpeg-6b-r5 to /
* Adjusting permissions on ccache in /root/.ccache

My question is about this adjusting process, each adjusting process longs
about 4 to 5 seconds. For whole update this makes 54 to 67.5 minutes and if
this really is only an permission adjusting process i thought this is just
loosing time. Can you help to understand this and if there is a settings for
this that i missed would you show me?
