Build Problem on OS X

I have a problem building Firefox on OS X. I used to do it without 
problems, but for some reason I am having some problems now. When the 
build completes, I have a Firefox.app which is 353 Megs in size. That 
just cannot be right. When I used to build my own before it was MUCH 
smaller. Here is the configure line from my config.status file:

# ./configure --disable-ldap --disable-mailnews 
--enable-extensions=cookie,xml-
rpc,xmlextras,pref,transformiix,universalchardet,webservices,inspector,gnomevfs,
negotiateauth --enable-crypto --disable-composer --enable-single-profile 
--disab
le-profilesharing '--enable-optimize=-O2 -g' --disable-debug 
--disable-tests --e
nable-static --disable-shared --enable-prebinding


As you can see I am disabling debug and disabling tests. How come my 
build is so big?

Thanks,
Jeff
