I agree this is confusing. Our build process generally produces way
too much output, and not always useful information. FOr the site.cfg,
there are a lot of possibilities, I think the whole process is a bit
too smart for its own good, but it is hard to change without breaking
someone else workflow.

I will take a look at the code to see if it is doable to print the
actual site.cfg used if it is indeed used.

Yes, it seems. To be honest, I never used this feature, I am surprised
myself it picked up $HOME/site.cfg.

This the fortran wrappers of the ATLAS are broken, I am not sure it is
such a great news :)
