Based on code Chad (hunmunk) posted, I've drafted a Dependencies module,
http://drupal.org/node/57071, that tests for dependencies and doesn't allow
modules to be installed if their dependencies are missing. You could include
a _dependencies() hook, e.g.
return array('module1', 'module2');
Of course, that will work only if a site has the Dependencies module
installed and enabled.
Or else feel free to just add your dependencies to the default array in the
dependencies/dependencies.module (this goes for any other module developer).
Robert Douglass suggested, and I concur, that it woud be useful to
distinguish between hard and soft dependencies, but I haven't yet
incorporated his suggestion into the module.
