ccache on amd64

[Brian]

Has there been any change in the above?  On a single core i386, the 
documentation described notes work properly.  However, on a AM2 based 
machine with the amd64 version of freebsd (both 6.4 Beta and 7.0 show 
this behavior) I consistently get the below error.

I have followed the listed instructions, and the above persists.
