Here is my make.conf file that you requested. Just for your info. I performed a stage 3 install.
The only things that I added were USE flags and sync mirrors and MAKEOPTS per the install instructions.
# These settings were set by the catalyst build script that automatically built this stage
# Please consult /etc/make.conf.example for a more detailed example
CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer"
