Probably a Debian package would be a nice way to run Ostrich. But don't spent time for me, I can manage to build it natively or in Docker. I already started to create a Docker image (details in the readme) https://github.com/apache/marmotta/blob/900a70cfd33ceafb1513e8ecd41df9bd25fb42b9/libraries/ostrich/backend/Dockerfile#L52 but I get the same error than building locally: -- Boost version: 1.55.0 -- Found the following Boost libraries: -- iostreams -- Not Found Tcmalloc -- Enabling gzip/bzip2 support (Boost iostreams found) CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: PROTOBUF_LIBRARY (ADVANCED) linked by target "marmotta_model" in directory /src/model linked by target "marmotta_sparql" in directory /src/sparql linked by target "marmotta_service" in directory /src/service linked by target "marmotta_persistence" in directory /src/persistence linked by target "marmotta_sharding" in directory /src/sharding linked by target "marmotta_client" in directory /src/client -- Configuring incomplete, errors occurred! See also "/src/build/CMakeFiles/CMakeOutput.log". See also "/src/build/CMakeFiles/CMakeError.log".

That's not needed if done properly and unnecessarily wastes a lot of space. I only need 4 different permutations, and I have a context/named graph in addition to SPO. Yeah, I find that hexastore a bit naive too, but I was not sure about the LevelDB query capabilities to really judge it.
