Comment 2 for bug 70315

I wasn't really worrying about the lib32 directories (though now I think about it, that's rather odd too), but rather suggesting that either the include line in /etc/ld.so.conf should read:

include /etc/ld.so.conf.d/*

Or probably better, that /etc/ld.so.conf.d/x86_64-linux-gnu should instead be named /etc/ld.so.conf.d/x86_64-linux-gnu.conf so that the existing include line actually reads it. That's more robust against editors which leave backup files behind.

Does your system have the same "include" line as mine in /etc/ld.so.conf?
