Well, I guess, you can start your compiler via "make -j 2" and/or put
something like "make_options = -j2" into "/etc/apt/apt-build.conf" (but
I'm not sure about the correct syntax for apt-build.conf).
The "-j" option of the "make"-command specifies the number of jobs to
run simultaneously. You have a dual-core, so I guess -j2 is a good
start. Maybe -j3 or even more may give you some more speed, you'll have
to try...
You could also disable optimization in gcc (the -O switch), which speeds
up compiling. But that would result in slower/bigger binaries... so i
guess that is not what you want... ;-)
HTH,
