Let me see if I got this right. :-) There is a way to masq distcc (as 
documented below), what I don't understand is how to masq ccache with distcc.

I have no CCACHE or DIST_CC env variables.

$ which gcc
/usr/libexec/distcc/bin/gcc

Gives me my masquerade version of distcc 

$ ls -l /usr/libexec/distcc/bin/gcc
/usr/libexec/distcc/bin/gcc -> /usr/bin/distcc*

$ cat $HOME/.distcc/hosts
cluster00
cluster01
cluster02
cluster03
cluster04
cluster05
cluster06

Got my distcc hosts setup as above.

$ which ccache
/usr/bin/ccache

Got ccache in my path, so I normally do this:

$ make CC="ccache gcc" -j10

The works great for most things, but as discussed on this list libtool can be 
a pain dealing with the "ccache gcc" thing.

This thread caught my attention because of the ability to masq ccache. I've 
done this with a shell script in $HOME/bin/gcc and having it early in my 
path,  and looks like this:

#!/bin/bash
exec /usr/bin/ccache gcc $*

Is there a better was to masq ccache and distcc without using a shell script 
as above?
