Hmm, I might be misinterpreting the output of "ldd", it looks like it reports the dependencies of dependencies not just the direct dependencies. "readelf -d" seems more reliable. [csamuel@farnarkle2 libtool]$ readelf -d libhhgttg.so.1 | fgrep -i lib 0x0000000000000001 (NEEDED) Shared library: [libmpi.so.40] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] 0x000000000000000e (SONAME) Library soname: [libhhgttg.so.1] Whereas the HDF5 libraries really do have them listed as a dependency.
