Thanks for having improved my understanding :-)

I do use Geant4.9.4. I do have /usr/lib64 but it is not a symlink, rather an empty directory. And based on my (current) understanding of the section, this is the source of my (or Archlinux's) problem because the outer condition holds true but no libraries are subsequently found. I wonder if this "having empty non-symlinked lib64" is a unique "feature" of Archlinux or if it occurs in any other distributions as well.

Nevermind. Archlinux is not among supported distros and I was able to solve the problem on the spot by changing one line in the script. Still I think this is an interesting issue to point out.

Cheers, Jan
