I found the problem: the linker was silently balking at creating the .sos and not telling 'make' about it, so a full build was done without the shared libraries. It's a GNU linker/autoconf issue that the MonetDB team can't do much about besides posting this email where Google will find it, but thank you all for helping me diagnose the issue. Now I just have to work with the memory leak I'm seeing. I see I can log all memory operations, but where can I set memory usage to be limited altogether?
