you will still need to create a modulefile for the gompi toolchain, this
is done as explained later in the step by step guide, but I have added
this now as step 3.2
eb gompi-1.4.10.eb
This will create a module which does nothing more then load the 2
dependencies, so after this easybuild will be able to actually use the
gompi toolchain.

the gompi module is not listed there, so easybuild can not use it yet.
However, easybuild could easily create it for you if you use the `-r` or
`--robot` option (but we don't show this in the step by step guide,
since this guide shows you all the steps instead of letting easybuild do
everything for you)
if you run
eb OpenBLAS-0.2.6-gompi-1.4.10-LAPACK-3.4.2.eb
<https://github.com/hpcugent/easybuild-easyconfigs/blob/master/easybuild/easyconfigs/o/OpenBLAS/OpenBLAS-0.2.6-gompi-1.4.10-LAPACK-3.4.2.eb>
-r
EasyBuild will doe a recursive build, so figure out all the modules it
needs to build, and build them for you, so you don't have to do the step
by step thing.
So this is why the quick demo will also work, it will build al needed
dependencies for you without any of your intervention since it has the
--robot option
