minefield for mac

What is the most minimalist possible minefield? Right now [here] it  
takes forever to start up and it's very slow. Is there any  
"liposuction" that can be done to trim the extras? I want it to be as  
fast as possible and I don't care about its looks. [For example] I  
have font smoothing disabled globally on my machine, for the sake of  
better performance, and yet it seems that minefield doesn't give a …  
about it and smooth the fonts anyway.

## Here is how I build it:

$cd "~/mozilla/"\
&& /opt/local/bin/cvs up -A client.mk\
&& /usr/bin/make -f client.mk build MOZ_CURRENT_PROJECT=browser#  
export MOZCONFIG=~/mozilla/mozconfig-firefox

## Here is the mozconfig file

$ cat mozilla/.mozconfig
# My first mozilla config

mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-@CONFIG_GUESS@

. $topsrcdir/browser/config/mozconfig
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/ff-opt-static
ac_add_options --enable-optimize
ac_add_options --disable-debug
ac_add_options --enable-static
ac_add_options --disable-shared
ac_add_options --disable-libxul

## Here is my machine's specification
