Hi all, Being faced with similar questions (which module depends on which) I wrote a small utility to compute dependencies from a directory of module files (hence it is not specific to EasyBuild). Given a module name, it will recursively list all dependencies or reverse dependencies.
It is certainly rough around the edges, but it serves my needs. If you like to try it, feel free: https://github.com/gjbex/vsc-module-dependencies It requires Python 2.7.x.
