is BOINC referencing a different dynamic linker than clinfo?

The driver is definitely installed. I can run OpenCL code and CUDA code from the command line. BOINC runs CUDA apps fine. BOINC just thinks it can't find libOpenCL.so. Is BOINC using static paths for libOpenCL, rather than letting ld.so find it?
