It is commonly used on HPC clusters. It is included in ports as sysutils/modules The stock installation of sysutils/modules includes a configuration file: /usr/local/Modules/3.1.6/init/.modulespath This is what is in the file: # # @(#).modulespath.in 1.3\t95/08/06 # Module version 3.1.6 # # Modulepath initial setup # ======================== # # This file defines the initial setup for the module files search path. # Comments may be added anywhere. The 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 variable size of your shell. # /usr/local/Modules/versions # location of version files /usr/local/Modules/$MODULE_VERSION/modulefiles # Module pkg modulefiles /usr/local/lib/ # General module files # /usr/local/Modules/3.1.6/your_contribs # Edit for your requirements If you try to add a new path to the list (at the bottom), the program segfaults and dumps a core in the current directory. >How-To-Repeat: Install sysutils/modules, add a new path to the end of the .modulepath file. Run 'module avail'. (Modules is usually setup as part of a shell function, to test it directly, run '/usr/local/Modules/3.1.6/bin/modulecmd bash avail` (or zsh, or tcsh, etc...). >Fix: The problem is that /usr/local/lib is getting added as a location for possible new module definitions. Something in the parsing of /usr/local/lib is causing the program to segfault. Commenting out /usr/local/lib solves the problem. >Release-Note: >Audit-Trail: >Unformatted:
