Hi. Sorry, the patch is wrong, as it was against the unstable version, and I missed there is even an hyphen in debian/rules here:
-LD_LIBRARY_PATH=$(shell pwd)/$(shell ls -d obj-*) dh_auto_test I think that's exactly the spirit of my previous "|| true" suggestion (which I did before I saw the hyphen). So, I believe we should just backport that hyphen to bookworm. Simple and effective. I don't like NMUs but I would be willing to help with the bureaucrazy if you accept a sponsored upload. Thanks.
