The problem is that there are multiple versions of the hdf5 package. Octave was written with the serial version in mind but it is likely to work with the others (OpenMPI and Mpich). Due to the naming scheme done in Debian, it may be required to specify the location of the libraries. See bug {{bug|38928}} for details (starting with comment #19) but basically, use the following when running configure: | The problem is that there are multiple versions of the hdf5 package.
