On VSC-4 and VSC-5, spack is used to install and provide modules, see SPACK - a package manager for HPC systems.

In order to set environment variables needed for a specific application, the module environment may be used:

module avail lists the available Application-Software, Compilers, Parallel-Environment, and Libraries
module list shows currently loaded package of your session
module unload <xyz> unload a particular package <xyz> from your session
module load <xyz> load a particular package <xyz> into your session
module display <xyz> OR module show <xyz> show module details such as the full path of the module file and all (or most) of the environment changes the modulefile will make if loaded
module purge unloads all loaded modulefiles

Note:

<xyz> format corresponds exactly to the output of module avail. Thus, in order to load or unload a selected module, copy and paste exactly the name listed by module avail.
a list of module load/unload directives may also be included in the top part of a job submission script

When all required/intended modules have been loaded, user packages may be compiled as usual.

If a new directory in the top level of the module directory structure is created, the MODULEPATH environment variable needs to be adjusted in this file:

/opt/sw/x86_64/glibc-2.12/ivybridge-ep/modules/3.2.6/gnu-4.4.7/Modules/3.2.6/init/.modulespath

#  Modulepath initial setup
#  ========================
#
#  This file defines the initial setup for the module files search path.
#  Comments may be added anywhere, which begin on # and continue until the 
#     end of the line
#  Each line containing a single path will be added to the MODULEPATH
#     environment variable. You may add as many as you want - just
#     limited by the maximum variable size of your shell.
