----------------------------------------------+-----------------------------
 Several Linux distributions have already started to move their libraries
 to a new directory structure that reflects the target architecture and
 allows the installation of packages from multiple architectures in the
 same system. The following links provide more details of this change:

 https://wiki.ubuntu.com/MultiarchSpec
 }}}

 This change potentially affects several of external library scripts
 shipped with ET. For example the HDF5/src/detect.sh script is not able to
 detect the hdf5 libraries installed in the directory /usr/lib/x86_64
 -linux-gnu for Ubuntu 14.04.2 LTS.

 I have attached a simple patch to remedy this issue and open a discussion
 on the best way to proceed here. This patch does depend on the
 availability of gcc on the system. It currently works fine for me, but we
 might need a better solution for systems without gcc.
