Replying to [comment:5 drkirkby]:
> The problem with updating ATLAS is the package is so messy. I looked at
building it in parallel (it's clearly designed for that, and has options
specifically for parallel builds), but it failed for me. Given it takes a
long time to build if the system is unknown, it would be nice to get
parallel builds working. There are special configure options for using a
parallel make.
Is there a system on which ATLAS does build / tune successfully in
parallel?
> I'd be tempted to re-write the whole package as /bin/sh shell script.
Remove the python, remove the perl. But some might object to that. I can't
see why we should have to wait for python to build before building ATLAS -
it would be sensible to get ATLAS building as soon as possible.
We'll also need to do the same with the Fortran spkg, in order to start
building ATLAS earlier in the Sage build process. If this will help
generally and significantly with parallel spkg builds, we ''might''
convince others that this worthwhile. Of course, we'll need to test it
well.
Can we use bash and its `$RANDOM`?
