Humm... This works fine in user mode... But, I don't understand why,
if I commented all ccache flags in make.conf an .cshrc's root, with or
without CFLAGS, in make.conf, etc, the output *was* the same???

This works fine under a normal user. Under root... also!!!
(note that I really make a strong verification about ccache use;
deleted from make.conf, deleted from .cshrc's root and deleted port
ccache).

One thing I don't know about it, is the "cc1"... There isn't any "cc1"
in the system, and also anything about ccache with it (sorry for my
bad english).

I'm trying to make a buildworld now, and at the moment... But here it
is; without ccache and only with system's gcc:

This is without ccache and with CFLAGS... :-/
Really... I don't know what to do... :-(

Thank you Jeremy.
