And there lies the problem. The package is build for 64bit on amd64 only
and 32bit on i386. So it needs to be:
if (arch is x86-64) {
path = /usr/lib64/dri:/usr/lib/dri
} else if (arch is i386) {
path = /usr/lib32/dri:/usr/lib/dir
}
I.e. look in both places.
Alternatively this could switch over to use the multiarch directories:
path = /usr/lib/$(DEB_HOST_GNU_TYPE)/dri
