Hi all,

The problem came back in Ubuntu 15.04 none of the previous solutions
work this time.

I have both libraries installed (apparently it is allowed in 15.04)

MPI (version 1.8.13)
/usr/include/hdf5/openmpi/hdf5.h
/usr/lib/openmpi/include/mpi.h
/usr/lib/x86_64-linux-gnu/hdf5/openmpi/libhdf5.a
/usr/lib/x86_64-linux-gnu/hdf5/openmpi/libhdf5.so

SERIAL
/usr/include/hdf5/serial/hdf5.h
/usr/lib/x86_64-linux-gnu/hdf5/serial/
/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5.so
/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5.a

The solution for configure this time requieres extra folders, since it
seems everythgin has been distributed around

CFLAGS="-I/usr/lib/openmpi/include -I/usr/include/hdf5/openmpi"
CPPFLAGS="-I/usr/lib/openmpi/include -I/usr/include/hdf5/openmpi"
LDFLAGS="-L/usr/lib/x86_64-linux-gnu/hdf5/openmpi/" ./configure

However compilation fails
