Comment(by leif):
P.S.: I guess you'll already know, but you can build Sage in parallel by
doing:
{{{
#!sh
export SAGE_PARALLEL_SPKG_BUILD=yes
export MAKE="make -j4" # build with 4 jobs (threads)
make
}}}
Depending on your machine (number of cores and amount of RAM), you can
also use larger numbers, i.e. more jobs.
On my Core2 quad, building Sage (from scratch) that way takes about 27 +
18 minutes (code + documentation; the latter unfortunately doesn't make
use of more than one core, which is subject to change soon).

To watch ATLAS's progress, you can open another terminal window and do
{{{
#!sh
tail -f $SAGE_ROOT/install.log | grep STAGE
}}}
after starting `make`. (Actually you can also start it earlier; `tail -f`
won't terminate by itself, i.e., you'll have to terminate it by pressing
Control-C anyway.)
