@RvDijk urgh, as you maybe noticed, including libxml2 as a dep now is an issue because this HDF5 is used as a dep in places where libxml2 is already a dependency too, so both the version and versionsuffix of libxml2 must match.

There are a handful of easyconfigs that seem to depend both on this HDF5 and libxml2 2.9.3 with -Python-2.7.11 as versionsuffix, i.e.:

• MDSplus-7.0.67-foss-2016a-Java-1.7.0_79-Python-2.7.11.eb
• NCO-4.6.0-foss-2016a.eb
• libdap-3.18.1-foss-2016a-Python-2.7.11.eb

So, if you want to go through with this, you'll need to see what the libxml2 with Python bindings is really required for these, and if not, drop the versionsuffix for libxml2 in them...

With this in mind, it's probably going to be very painful to add libxml2 as dep in all existing HDF5 easyconfigs, but we should try and do it for at least the most recent ones...

@boegel this seems to work on Travis, except for the newer lmod versions. If this is what you had in mind, then I'll also change this in other versions of HDF5.

(close/open to retrigger Travis with correct config)
