OpalRunner: Loading of libraries does not work

The module file that should load all OPAL dependencies is not working.

This does not work:

module use /afs/psi.ch/project/amas/modulefiles
module load opal-toolchain/master

This works:

module use unstable
module load cmake/3.9.6
module load gcc/7.3.0 
module load gsl/2.5
module load openmpi/3.1.3
module load boost/1.68.0 
module load hdf5/1.10.4
module load OpenBLAS/0.2.20 
module load H5hut/2.0.0rc5
module load trilinos/12.12.1

Is this a bug in the opal-toolchain?
