Unfortunately, that functionality fell into disrepair - it is scheduled to be repaired/replaced in v1.7.2.

That also means no NFS, so it's kind of nice to have the binary distributed by the root node. I configured with --disable-dlopen, and use -x PATH -x LD_LIBRARY_PATH in the mpirun invocation. As I said, it works fine if the binary is pre-distributed, but the --preload-binary and ---preload-files options both cause this problem. This problem occurs with the head node and one slave---I haven't tried larger configurations.
