Ok. For some reason I do not understand weyl_characters.py seems to be
much slower (in proportion) on 32 bit machines compared to 64 bit
boxen.

I feel you pain. I have access to a Mips64 machine we are porting Sage
to and its CPUs are 500MHz. So even when using six CPUs building Sage
takes about 18 to 24 hours of realtime (assuming one would get Sage to
build out of the box). There is little we can do there. A couple
things;
* export MAKE="make -j2" to build with two threads
* doctest with sage -tp 2 /devel/sage/sage - that way you use both
cores in parallel
I tend to build Sage before I go to sleep, so usually I wake up to a
new and shiny Sage once I am awake again :)

Is there any specific component that causes trouble? I.e. is ATLAS
slow to build for you?
