Can you add a /etc/ld.so.conf as well? On my debian this only contains
'include /etc/ld.so.conf.d/*.conf'. It would be great if we can do that
to. Then other packages can provide files there.
Juergen: You had some other version of this somewhere. Can you take a look
at this? I think you had some extra paths for Qt, right?
