+description: """
+The build section merits an explanation.
+
+(1) for debian 11/12, conf-rocksdb ensures that rocksdb gets installed.  But it'll be backlevel,
+and specifically either 5.17.2 or 6.11.4 -- versions that do not come with pkg-config files.
+So we just skip the test.
+
+(2) For all other OS versions, we check what pkg-config says.
