I have tried a parallel build of Atlas without success (using
GCC4.2.2). But then I am building on an i5-750 which won't build
Atlas3.8.3 in the sage sources.
I have now got Atlas3.9.25 to build. The spkg-install-script is
somewhat specific to my machine at the moment- for some reason it will
only compile when I explicitly pass the CPU clock frequency to
configure.

Like you, I've had trouble with a parallel build. But I note there is an option
on the configure script for this. So I'm wondering if that is the preffered way
to do this, rather than issue 'make -j 12' or similar, but instead to use the
'-Ss pmake' (IIRC) option.
I don't know how practical it will be to try to fix the Makefile(s) that are
presenting the problem.
On 't2', it takes over 7 hours to build ATLAS. I've done it in 50 minutes with a
parallel build, but I'm not comfortable it is reliable.
I think we need to find out how one is supposed to build ATLAS in parallel - it
might not be as obvious as we think.
